2 CMS Experiment

U. Mississippi is a founding member of the CMS collaboration and has participated in (1) the HCALconstruction project with contribution of fiber channel readout boxes (RBX’s) and the HCAL fibersplicer. The Mississippi ”plastic” fiber splicer has also been used for other fiber relate projects atthe FNAL splicer facility and TRIUMPH. (2) U. Mississippi was also involved in prototyping of theCMS Forward Pixel mechanical structures and cooling channels. The present pixel wheel supportingand cooling structure is based on a brazed/machined Al cooling channel which we introduced andprototyped.

On the HCAL we have continuing involvement in the M&O phase with contributions to HCALcalibration group looking in to jet-scale calibration with tt events. In Pixels we are participatingin the development of the pixel detector control system (DCS) with colleagues at Fermilab. Weare involved in SLHC R&D involving the replacement of the HE with a more radiation tolerantquartz device with U. Iowa. We have a small R&D effort in to looking at possibility of increasingthe radiation hardness of silicon with ultrasonic treatment.

Building on research from the BABARand the D∅ experiments, and with joint activities with ourGravitational Physics group at UM we are exploring CP violation in the top sector, and productionof mini black holes at the LHC.

2.1 Jet Scale Calibration with t -tbar Events for CMS

The inclusive tt production cross section at the LHC will be approximately 770 pb [1] for a top massof mtop = 175 GeV/c2. The LHC will collect about 104pb−1 per year in low luminosity running. Itwill then be possible to use these events in jet-scale energy calibrations. We consider HCAL/ECALcalibration with t t → Wb Wb → lvb jjb events. A good double b-tagging algorithm for isolatinga clean top sample will be needed to isolate top events in the high mass backgrounds.

We began the project in CY06 by producing a Pythia-level generation code for tt events andbackgrounds, and a fast CMS ECAL/HCAL response algorithm for jet reconstruction. We arestudying the jet energy correction α

EJet =α(R, η, φ)× (ECal − E0)

<(R, η, φ) S(R, η, φ).(1)

< and S are calorimeter response and reconstruction containment corrections, which must be ex-plored with the full CMS GEANT simulation package CMSSW and data.

In Figure 1 we plot the fitted-number of top versus jet scale α. In Figure 2 we plot the effectivenumber vs. α. We have shown an interesting result, that the optimum jet scale correction occurswhen signal-to-noise or Neff = (Ntop/σtop)

2 is maximum.We are attending the HCAL Calibration Meeting (VRVS) headed by M. Valesco (Northwestern

U.), and S. Kunori (U. Maryland) on a regular basis. The meetings are presently focused on detectorlevel calibration and higher jet-level calibration discussion is set for the future.

Figure 1: t → bW → bjj events |η| ≤ 1.5, pT ≤ 30 GeV/c. Signal Yield = 5150 ± 80. The fittedsignal has a typical mass Mo = 182 GeV and a width of σ = 14.1 GeV.

2.2 Studies of CP Violation in the top quark sector at the LHC.

Over the past years the Mississippi HEP group has developed an expertise in CP physics atBABAR and KTEV. The research direction fuses work performed at the D∅ experiment in topphysics with future work at the LHC. Dr. Quinn has submitted an OJI proposal to the DoE furtherdiscussing research, some of which is described below.

CP Violation w Top The large top quark mass mt ≈ 175 GeV/c2 forces the weak decay timescale τW ≈ 10−24s to be an order of magnitude shorter than the QCD time evolution. The topquark will decay directly via t → W+ + b before hadronizing. We see that the dynamics of topformation and decay are ”bare” and are not masked by QCD effects. Any resulting CP phenomenarelated to the top quark will then be of a ”direct” nature.

With the large tt cross section at the LHC w (107-108) top pairs will be created per year. Studiesin to CP violation in the top sector will be of major importance at the Tevatron and in the firstyears of running at the LHC.

The SM predicts the CP -violating effects for the top to be very small, due to the top’s high massand subsequent effective GIM cancellation of standard CP effects. Any observation of CP -violatingeffects in the top sector would indicate a beyond-SM phenomena. In some models the coupling ofthe top quark to CP -violating phases in beyond-SM physics are able to supply the CP -violationnecessary to drive baryogenesis, the idea that baryons and anti-baryons interact with different ratesin the early universe, resulting in a baryon dominated universe.

A CP -odd phase due to an extended neutral Higgs sector or vertex correlations arising in otherextentions of the standard model can endow the top quark with a large dipole moment form factor.CP violation in the neutral Higgs sector and in supersymmetry can have interesting effects in thesingle top production at the upgraded Tevatron pp collider and in tt pair production at the LHC. [1]CP -odd phases in SUSY produce interesting assymetry effects in the partial decay rates t→ W+band t→ W−b

We are presently exploring two types of CP searches to be performed at the LHC with either

leptons or tagged jets, (1) Partial Rate Assymetry (PRA), and (2) Energy Assymetry AE.

Γ(t→ bτ+ντ ) + Γ(t→ bτ+ντ ),

AE =Eτ+ − Eτ+

,

and leave further discussion for the future.

2.3 Mini Black Hole Production at the LHC

The early universe is often considered to be the only instance of a situation in which quantum andgravitational processes are equally important. However black holes with small masses, if they exist,could be the only objects in today’s cosmos where such an extreme gravitational/quantum objectmight exist. These small black holes may have been produced in the early universe thanks to densityfluctuations and with masses that are arbitrarily low. With the idea of ”large extra dimensions” putforth some years ago the, these mini black holes need not have formation scales of the Planck length

`P =√Gh/c3 ≈ 10−33 cm (corresponding Planck formation energy EPl = c4/GlP ≈ 1019 GeV), but

can have large dimensions of up to 1 millimeter! The effective Planck scale energy ED in our 4Dworld is reduced to

ED = (E2Pl/VD−4)

1/(D−2) (2)

where VD is the volume of D-4 extra dimensions [2]. For (dimension) D=10, ED ≈ 1 TeV , RH ≈10−4fm, well within the reach of the LHC.

6

For parton impact parameter b ≤ RH mini black hole production might follow a simple geomet-rical cross section σH = πR2

H ≈ 1nb producing of order one mini black hole per second at the LHC.The mini black holes (M≈100GeV) are expected to evaporate in to Standard Model particles inof order 10−24s, with signatures of high Pt, high multiplicity, and equally coupling to all particlesdemocratically.

Working with a model provided by Dr. Marco Cavaglia, Dr. R. Godang and Dr. D. Summershave produced Pythia events on the local farm systems and has run them through the CMSSWGEANT simulations at Fermilab. We are in progress of analysing these events and comparing themto more generic high Pt events produced at the LHC. The subject is discussed further in section 5.

2.4 Pixel Slow Controls and CMS Computing

DCS The University of Mississippi has been both active in the “Slow Controls” of the Pixeldetector and has started working on the preparation for the upcoming “Slice Test” and CERN Testbeam running. David Sanders attended a workshop during the week of July 25-29, 2005, on PVSS,the LHC slow controls software, and has installed PVSS software on one computer at Mississippifor testing. He also attended the September 9, 2005 LPC Slice Test Meeting at Fermilab.

CMS Computing We have begun testing CMS software on one node of our new computingfarm, with the eventual intention of migrating from primarily D∅ to LHC work. Romulus Godangis integrating one node into the LHC grid system. We have installed the main grid software, theVirtual Data Toolkit (VDT) and are conducting preliminary tests.

Status of RAID Arrays In the past we built at UM and provided 2 x 1TB RAID arrays to CMSused in MC event generation by Princeton’s Tony Wildish and by Lucia Silvestris of the Si Tracker.Commercial RAID arrays are now relatively cheap and we have halted our R&D, previously basedon cost optimization. We have setup one of our RAID arrays as a “mirror” site. This allowsthe installation and updating of software for the computers in our computing farm to downloadsoftware over our local Gigabit link rather than from the Internet. We maintain a local copy of bothScientific Linux operating systems (3 and 4) as well as Fedora, Mandrake, Suse, etc. Another RAIDarray, returned from SLAC, has been used by Marco Cavaglia as part of his black hole simulations.

2.5 SLHC Calorimeter R&D and Silicon Detector Research

SLHC We have begun two new R&D programs mainly involving faculty and students. In Su-perLHC R&D the U. Iowa, U. Mississippi, Fairfield groups are studying the possibility of outfittingthe HE calorimeter with a more radiation hard quartz plate technology. Since the calorimeter reso-

lution scales with light photo-election (pe) collection σE ≈ 1/√Npe the loss in Npe in transitioning

from scintillator to quartz must be replenished.Iowa is focusing on the quartz plates and readout fibers and Mississippi has introduced the

novel idea of enhancing the light output with a coating or wrapper of Pterphenol WLS/scintilattor.Test show that even a thin layer of PTP on quartz plates surface gives a large gain in light yield.Radiation testing with e/γ/p/n radiations are in progress. In Spring and Summer 2006 prototypecalorimeter will be placed in the Fermilab and CERN testbeam.

Advanced Silicon R&D Nuclear radiation will generate point defects in Si and change thefundamental properties of charge transport and collection in these devices. Traditional annealingwith heat is limited in application to initially prepared thin wafers or bulk samples. The thermaltreatment is shown to alter oxygen and carbon concentrations in Si and other defect subsystems,but is limited in scope.

We are investigating the possibility of improving detector performance by a relatively new tech-nique of ultrasonic defect manipulation (UDM). This novel approach was developed by Dr. IgorOstrovskii. We have shown that in bulk CZ Si, which has been irradiated with neutrons, an ul-trasonic treatment will increase the samples conductivity and flush certain impurity radicals to thesurface [3]. The measurements were performed in Kiev where neutron irradiation and SecondaryIon Mass Spectrometer (SIMS) were available. Further study will require Deep Level TransientSpectroscopy (DLTS) system not available to us in the U.S. or Transient Current Technique (TCT)which we are considering.

2.6 QuarkNET

The U. Mississippi QuarkNET chapter added two new members in CY05. Our summer workshopwas conducted at Fermilab with the teachers making on-site visits to CDF and D∅ . They alsoworked on a bubble-chamber reconstruction project in which they learned to measure momentumvectors from bubble chamber events.

The group has submitted a FNAL Summer Quarknet Workshop proposal to work on threeprojects (1) Continuation of Bubble Chamber event reconstruction, (2) Building of an inexpensiveclassroom medium-sized Cloud Chamber, and (3) producing a Quarknet Cookbook with simpleclassroom experiments to perform which tie particle physics to other curricula as Algebra, Calculus,Geometry, etc.

James Reidy Jr. worked as a CMS fellow during summer 05 with the HEP group. We workedon muon counter trigger electrons and paddles. We successfully operated the Notre Dame Imageintensifier array and took some digital movies of cosmics.

3 BABAR Physics Analysis

3.1 Branching Fraction of Υ (4S) → B0B0

Romulus Godang has completed the the first measurement of the branching fraction of Υ (4S) →B0B0 using partial reconstruction of B0 → D∗+`−ν`. He introduced a novel technique for thisanalysis in which he compared the single and the double tag samples of B0 → D∗+`−ν` to extract aresult independent of the branching fractions of the B0 and the D∗+ decays, of MC reconstructionefficiency, of charged and neutral B meson lifetimes, or of the assumption of isospin symmetry. Themeasurement yielded a result of

f00 = 0.487± 0.010(stat.)± 0.008(sys.).

This analysis has been published in PRL 95, 042001 (2005).

3.2 Search for Rare Decay B0 → D∗0γ

Johannes Bauer completed his blind analysis in the search for the rare decay B0 → D∗0γ in 2005.In February ’05, the signal box was unblinded and the analysis was sent to collaboration-widereview; in March ’05, the preliminary result was presented at the Moriond conference. In June, thejournal paper was submitted to Physical Review D Rapid Communications, where it was publishedin Phys. Rev. D72, 051106 (2005).

This analysis is important to our full understanding of factorization and radiative penguindecays. This decay proceeding through W-exchange may contribute to some radiative penguindecays and must be considered for completeness. If the branching fraction is ≥ 10−6 new non-SMphysics may be present.

Figure 3 shows the ∆E-mES plane with the thirteen events in the signal box to the right. Sincea total of 9.4± 1.7 background events was expected, the analysis determined the upper limit on thebranching fraction for B0 → D∗0γ to be 2.5 × 10−5 at 90% confidence level. This limit is twice assmall as the previous limit set by the CLEO Collaboration.

3.3 Branching Fraction of D0 → K−π+

Dr. Godang is also finishing a new BABAR analysis on the measurement of an absolute branchingfraction of D0 → K−π+ using a 210 fb−1 sample. This precise measurement could help solve theCharm Deficit problem in which the sum-total charm BF is a bit too small and is very importantin normalizing many charm (D0) and b-meson BFs. He gave a preliminary talk on this topicat the BABAR Collaboration meeting at SLAC on December 2005. Preliminary results for thismeasurement will be reported at Moriond 2006. BABAR expects to reduce the errors on the BF bya significant factor of 2 over recent CLEO-c results [3]. Preliminary results are given in the Table1.

3.4 Studies of Hadronic Decay B → D(∗)π− and B → D(∗)ρ−, a1(1260)−

Haiwen Zhao is finalizing his analysis of hadronic two-body decays B → D(∗)π. Since the recentresults from color-suppressed decay B0 → D(∗)0π0 indicate a failure of naive factorization model,study of color-favored B → D(∗)π with improved precision are very important for the validationof an improved model of QCD factorization. This measurement is also important in normalizationof B and Bs decays at hadron colliders. See for example CDFII’s recent measurement of B(B0

s →D−

s π+)/B(B0 → D−π+) (e-Print Archive: hep-ex/0508014).

Based on a 59.0 fb−1 data sample on resonance he has measured the branching fractions forthe color-favored B0 → D−π+, B0 → D∗−π+, B− → D0π− and B− → D∗0π− decays. Usingthe measured branching fractions, the value of the cosine of the strong phase difference δI in theD(∗)π system, and the ratio of I3/2 and I1/2 isospin amplitudes are determined. The ratio of theeffective factorization parameters xa2

a1for both B → Dπ and B → D∗π processes are obtained. Our

results for cos δI suggests the presence of final-state interactions in B → D(∗)π decays. The resultis reported in Table 2.

The precision result is under review within the BABAR analysis working group and collaboration-wide review will soon to follow. The measurement results is planned to publish at Moriond 2006Conference with plans to publish in to Physical Review D in ’06.

The B → D(∗)ρ−, B → D(∗)a1(1260)− two-body and quasi-two body decays are important infactorization model tests and CP violation studies. Furthermore, the measurement of polarizationin the decay B0 → D∗−a+

1 (1260), which is a scalar to vector and axial-vector decay, could pro-vide important information in chirality tests and in resolving an ambiguity in the CP violationparameter 2β + γ. Dr. Zhao has obtained preliminary measurement results for B → D(∗)ρ−,B → D(∗)a−1 (1260), the polarization for B → D(∗)a−1 (1260) decays, and the longitudinal fractionin the decay is fL = 0.810± 0.042. Further study and systematic error estimation is ongoing. Thepreliminary results are reported in Table 2.

3.5 Studies of Hadronic Decay B → D0Jπ

−

Doctoral candidate Vance Eschenburg in conjunction with collaborators from Iowa State Universityis studying B− → D∗0

2 (2460)π− and B− → D01(2420)π− decays, under the supervision of Rob

Kroeger and Johannes Bauer.These states, D0

1(2420) and D∗02 (2460), are members of a spin-symmetry doublet that possess a

total angular momentum of j = 32

in the heavy-quark limit (HQET). Vance will improve the branch-ing fraction measurements of D0

1(2420)π− and D∗02 (2460)π− first seen by the CLEO collaboration 1

. This work is being carried out within the Exclusive Hadronic B Decays to Open Charm (BReco)Analysis Working Group (AWG) in which context Vance reports his progress. The analysis of thesenarrow states is well advanced. Some improvement is expected with the tuning of selection cuts

and more data added from Run-4. Preliminary results were shown at DPF2004.[8]. He hopes tocomplete his dissertation by May 2005.

The Mississippi and Iowa State groups are working to analyze the resonant sub-structure of thedecays B− → D(∗)+π−π− and B0 → D(∗)0π+π− in order to shed light on the wider D∗

0 and D1 j=1/2resonances with L=1 by exploiting the measured invariant D(∗)+π− and D(∗)0π+ mass distributionsand the angular correlations between the decay products. Vance supplies much logistical supportto this side of the effort as he needs the result of this study in fitting for his branching fractions. InFigures 5 and 6 we show the D(∗)π FY04 signals. Both the broad and the narrow resonances areevidence.

Dr. Kroeger has continued his work to reconstitute the calorimeter cluster position reconstruc-tion algorithm by a technique which fits the energy depositions to an analytic integration over aparameterized shower shape. The algorithm has been tested and shows marked improvement insingle photon position reconstruction, the impact on BABAR π0 → γγ mass resolution is modest,but further improvements are anticipated.

3.6 BABAR Service Work

Johannes Bauer continued as source calibration manager until Jan 1,2006, supported by VanceEschenburg. Both are experts in the use of the neutron-activated circulating source for low energycalibration. During data taking, the individual crystals of the calorimeter were regularly calibratedby the source calibration system (every few weeks). Dr. Bauer lead our paper review committee assenior research associate on BABAR.

Dr. Zhao has played a leading role on the Electromagnetic Calorimetor (EMC) Data QualityAssurance. He was appointed to be in charge of BaBar EMC data quality mornitoring and assuranceas EMC expert for Run4 data taking period (2004) and to continue through May contributing almosttwo years of service. His work included the new Monte Carlo data validation, new software releasevalidation and data format conversion mornitoring and validation, mornitoring of EMC online eventprocessing data and EMC online prompt reconstruction data to validate the data after processing.Dr. Zhao implemented a tool codes for display the stripchart of important quantities for EMC data,report on any problems in the data processed in the preceeding week on a weekly meeting of theBabar QA group, and coordinate with other EMC experts to fix the hardware problems.

Dr. Kroeger completed the last stage of their study of geometrical corrections to the calorimetercluster energy assignment. Mr. Roy presented some results in Summer-04 at the July BABAR Col-laboration Meeting. The algorithm is being tested on BABAR’s EMC π0 → γγ mass resolution.

Dr. Godang serves as a BABAR Computing Model Expert. As a CM2 Expert he providesadvice on physics skims and general optimization of BABAR computing operations. In CY05 he ranadvanced CM2-Run4 skims of BABAR data. The data was used by INFN Sezione Di Padova groupfor their physics analysis topic:B0 → π−`+ν using partially reconstructed B0 → D∗+`−ν. These data ntuples can also be used forother analyses like determination of |Vub| using recoil technique.

Dr. Godang is serving with the Heavy Flavor Averaging Group (HFAG). He is managing anddeveloping world HFAG code (COMBOS). This work reports world averages for measurements onb-hadronic properties include B lifetimes, neutral meson mixing parameters, semileptonic decayparameters, rare decay branching factions, and CP violation measurements.

The U. Mississippi group (w Dr. Godang) submitted a proposal to BABAR for running at theΥ (5S) with the BABAR detector. at PEP-II, SLAC. We developed a measurement of absolutebranching fraction of B0

4 The D∅ Experiment

4.1 Introduction

The past year has been a prolific one for D∅ with regards to publications. From D∅ ’s first RunII supersymmetry search to the recently submitted full description of the D∅ detector, there havebeen 29 D∅ papers published in 2005, with three more submitted for publication. As a member ofthe top pair production group, Dr. Breese Quinn was most concerned with the initial results of ttcross section (σtt ) measurements using 230 pb−1 of integrated luminosity. D∅ reported on the ttcross section measured in the lepton+jets channel using kinematic event characteristics and usinglifetime b-tagging, and in the dilepton channel[1][2][3]. Dr. Quinn’s work has primarily been focusedon the lifetime b-tagging analysis which yielded a first result of σtt = 8.6+1.6

−1.5 (stat.+syst.) ±0.6(lumi). Figure 8 shows the tt lepton+jets data and Monte Carlo as a function of jet multiplicity.Dr. Quinn played a significant role on several papers for which he served as an editorial boardmember. These included measurements of the Λ0

b lifetime in Λ0b → J/ψΛ0 decays[4] and the lifetime

difference in the B0s system[5], as well as the first limits on single top quark production from D∅ in

Run II[6]. Another such paper is the full description of the Run II D∅ detector[7]. In other work,Dr. Quinn co-authored a paper on the electrical properties of carbon fiber support structures andtheir importance in silicon detector design[8].

Hatched areas represent totaluncertainty in the expected number of events. Excess events with three or more jets are interpretedas tt signal. Agreement between expected and observed events with jet multiplicity of 1 or 2validates the background estimation.

4.2 DOSAR

Much of Dr. Quinn’s research time in 2005 has been devoted to preparations for D∅ ’s near-termfuture. The next step for D∅ is the full analysis of the first 1 fb−1 of recorded luminosity. Toconsider this as one data set required reprocessing nearly 1 billion events with a single updatedreconstruction package. Also necessary is the generation of enormous sets of Monte Carlo events.

16

Ole Miss has participated in these efforts as part of DOSAR, a Distributed Organization for Scientificand Academic Research. DOSAR is a regional GRID computing consortium including nine D∅institutions whose combined resources are shown in Figure 9. DOSAR reprocessed more than 40million data events and has produced more than 30 million Monte Carlo events to date. In April,Ole Miss hosted the fifth DOSAR workshop which focused on extending the organization beyondD∅ to LHC experiments and other projects, and on joining the Open Science Grid (OSG). Dr.Quinn helped lead the effort to establish DOSAR as a Virtual Organization in OSG in June. Hepresented a poster on DOSAR at Lepton-Photon 2005[9].

Figure 9: DOSAR resources including GHz equivalent cpus, terabytes of data storage, and man-power.

4.3 SMT Layer-0 Silicon

The other major preparations for D∅ ’s future in which Dr. Quinn has been involved are the upgradesfor high luminosity running. The Tevatron will shut down for 14 weeks in the Spring of 2006 foraccelerator and detector upgrades. One of these upgrades is Layer 0 (L0), a new inner layer silicondetector to be mounted inside the current Silicon Microstrip Tracker (SMT). Dr. Quinn is leader ofthe L0 working group for Installation and Physics Commissioning. He and his group have produceda detailed, resource-loaded schedule for expedient L0 installation and commissioning which willreturn D∅ to physics-quality data taking as soon as possible after the spring shutdown (Figure 10).This work included recruiting and planning the effort of dozens of researchers and forming a newL0/SMT Software Group, led by Ole Miss postdoctoral researcher Dr. Alex Melnitchouk.

4.3.1 Layer-0 Software

Dr. Melnitchouk’s L0/SMT Software group has essentially completed the software needed to operateL0 and collect and reconstruct the data from L0 integrated with the current detector. In just oneyear dozens of software packages have been created and/or modified to handle L0 simulation, onlinecontrol, data packing and unpacking, clustering, tracking, and triggering. In the past month, L0cosmic ray data has been collected and reconstructed. Cluster energy distributions for the cosmicray data can be seen in Figure 11. This exercise has proven the functionality of the L0/SMT

software packages in advance of the installation date. Between now and that time, a program offurther code testing and optimization will be carried out.

Figure 11: Cluster energy distribution in ADC counts for cosmic ray muons in Layer 0 siliconmodules.

4.4 Higgs Boson Searches

Dr. Melnitchouk has worked on Higgs searches at D∅ for several years. His dissertation was onthe h → γγ analysis and he has since improved on that search by refining the photon selectionwith a neural net approach. He plans to perform this analysis again on the increased statisticsprovided in the reprocessed 1 fb−1 data set. Dr. Melnitchouk also presented a talk at PANIC 2005on Higgs boson searches in multijet events[10]. He has also recently been appointed to the high Pt

18

jet production editorial board.

4.5 CP Violation in top

Dr. Quinn has submitted a 2006 OJI proposal for a comprehensive program to search for CPviolation in the top quark sector at D∅ . A variety of observables associated with top pair and singletop production cross section, lepton energy, and spin asymmetries will be measured. Keys to thesestudies will be commissioning the new L0 silicon detector and maximizing its impact on trackingand b-tagging, applying the successful ’Matrix Method’ analysis strategy to new observables, andfor the first time including the high-statistics hadronic single top decay channel in a measurement.These asymmetries may indicate whether beyond-SM CP violation arising from the top chromo-electric dipole moment, or 1-loop interactions in 2HDM or MSSM account for matter-dominatedbaryogenesis. This is a research program that will naturally transition to CMS where the muchhigher statistics will increase the sensitivity to many CP violating asymmetries. An exception is CPviolation in s-channel single top production. s-channel production at the LHC will be overwhelmedby copious tt and W-gluon fusion backgrounds, so Run II at the Tevatron may be the only chanceto study this channel. Observing the s-channel asymmetries will depend on using the all jets singletop events, and Dr. Melnitchouk’s experience and position on the jet production board will beinvaluable. Continued postdoctoral support for Dr. Melnitchouk will be critical for the success ofthis project.

5 Neutrino Factory/Muon Collider Research

The University of Mississippi has been working on Neutrino Factory and Muon Collider R&Dsince 1994. Don Summers currently serves on the Neutrino Factory and Muon Collider executivecommittee. Summers, Godang, Bracker, and Cremaldi have made significant contributions to theproject. In previous years Mississippi help fabricate two 805 MHz copper RF cavities designed byLBL. The 805 MHz cavity has performed well in a number of tests in CY04.

In 2006, we propose to manufacture 201MHz RF cavity parts and aluminum LH2 windows forMICE. We plan to measure the LH2 MICE window thicknesses. We plan to do design work on aninverse sector cyclotron for 6D muon cooling.

5.1 201 MHz Cavity

In CY05 we participated in the fabrication of the first 201.25 MHz copper cavity [1] for the muonionization experiment MICE.12 The non-superconducting, high gradient (16.5 MV/m) 201.25 MHzis needed to provide re-acceleration in an ionization cooling channel and must operate in a multi-Tesla magnetic field. Demonstration of this type of cavity at high gradient in a strong magneticfield is a key milestone in establishing the feasiblity of a neutrino factory as a realistic choice ofnear-term facilty. The design is being tested in the new MUCOOL Test Area (MTA) at Fermilab.

The construction of this cavity has been a collaborative effort between JLAB(fabrication andassembly), LBNL(fabrication , engineering, and design), NASA Langley (e-beam welding), and theUniversity of Mississippi(fabrication) and was funded by the DoE.

Mississippi fabricated the stainless steel nose stiffeners, the copper nose rings, the manual tuner,the stainless steel side ports, and the equator weld fixture.

Figure 12: 201.25 MHz Cavity assembled at JLAB and shipped to Fermilab for testing at MTA.

5.2 MICE

One of the most important requirements for a neutrino factory/ muon collider is the ability tocool the muons to increase the phase space density. As all existing cooling techniques do not workquickly enough for muons, a new method has been proposed: ionization cooling. As this is an newtechnique, a series of experiments is being built to investigate the cooling process in some detail.MICE is the last and biggest of these and is being designed to show that ionization cooling worksand to learn more about the cooling process itself. The MICE experiment is approved forrunning at RAL with a staged beginning in 2007.

U. Mississippi and U. Louvain, Belgium, have been involved in the design and prototyping ofthe Cherenkov counters, CKOV1, CKOV2, as shown in Figure 13 for the Muon Ionization CoolingExperiment (MICE) at RAL. These devices will perform π− µ−e separation of the incoming (200-300) MeV/c beam.

The downstream cerenkov CKOVII detector has been designed and well understood. It is athreshold device using silica aerogel(n=1.03) as a radiator. It performs ON-OFF µ − e separationvery well. Muons will not give light until pµ ≥ 350 MeV/c, where electrons are well above threshold.

Figure 13: MICE cooling channel layout with CKOV1 and CKOV2 Cherenkovs.

The upstream Cherenkov CKV01 is problematic in that it must separate muons and pions verywell in a momentum range (200-300) MeV/c where no ON-OFF practical radiator is available. Weare looking in to a differential cherenkov design (DISC) Figure 14, where the pion ring is baffled(pion-blind) and light from the outer muon ring is collected in a series of PMTs. A RICH wouldsolve the probem, but quite an expensive solution.

5.3 Ionization Cooling Research

In order to achieve a future design for neutrino factory or muon collider, we have been performingionization cooling simulations with rings which is recently published [2].

In addition Summers and Godang are also are performing detailed simulations of ionizationcooling with a novel “inverse cyclotron technique”. which was presented at the COOL05 conference

[3]. Potentially the device may cool muons by a factor of a million which is enough for the realizationof a muon collider.

A large admittance sector cyclotron is filled with LiH wedges surrounded by helium or hydrogengas. Muons are cooled as they spiral adiabatically into a central swarm. As momentum approacheszero, the momentum spread also approaches zero. Long bunch trains coalesce. Energy loss is usedto inject the muons into the outer rim of the cyclotron. The density of material in the cyclotrondecreases adiabatically with radius. The sector cyclotron magnetic fields are transformed into anazimuthally symmetric magnetic bottle in the center. Helium gas is used to inhibit muoniumformation by positive muons. Deuterium gas is used to allow captured negative muons to escapevia the muon catalyzed fusion process. The presence of ionized gas in the center may automaticallyneutralize space charge. When a bunch train has coalesced into a central swarm, it is ejected axiallywith an electric kicker pulse.

Summer has published work on ”Alternating Gradient (FFAG) Rings” [5] and ”6D IonizationCooling with Tabletop Rings” [6]

Dr. Godang provided strong motivation for a Muon Collider also at DPF 04, now published [4]Briefly, in the s-channel Higgs production process to a narrow resonances nergy resolution is veryimportant consideration. [4] A muon collider with sufficient energy resolution (R = 0.01% and/or0.06%) might be the only possible means for separating the two higher mass Higgs bosons, H0 andA0. The s-channel Higgs resonance would be found by scanning in

√s using a small step (σ).

5.4 BH Phenomena at Muon Colliders

Summers and Godang are working with Dr. Marco Cavaglia in investigating the issue of BlackHole (BH) production at colliders.[4] If this fundamental energy scale for BH is as low as the TeVscale, BHs can be produced in future colliders such as the LHC, CLIC, and the muon collider. Asignature will be a large cross section of events with high missing ET . A black hole generator code

Figure 15: ICOOL simulation of single turn, energy loss injection. Three muons with identicalmomenta are injected into a low field cyclotron with four sectors, but with soft edged magneticfields. The inward spirals differ because of multiple scattering and straggling. The energy loss iscaused by radial LiH wedges surrounded by hydrogen gas. The amount of matter encountered ina given orbit decreases adiabatically with radius. The right trace shows that vertical motion iscompletely contained within ±5 cm along the 70m spiral. The fractional energy loss required in thefirst turn for injection increases with the width of the muon beam and decreases as the cyclotron’smagnetic field is lowered.

6 Gravitational and Theoretical High-Energy Physics Re-

search

Gravitational and theoretical high-energy physics research at The University of Mississippi (UM)spans a broad cross section of formal and phenomenological issues in particle physics and grav-ity. Research topics range from classical and numerical general relativity to gravitational waves,cosmology, string theory and ultrahigh-energy cosmic rays. The group has ongoing collaborationswith major U.S. institutions such as The University of Chicago, Fermilab, Washington University,Johns Hopkins University, Western Kentucky University, and foreign institutions such as PerimeterInstitute, Mexico University, Gent University, University of Rome, University of Bari and InstitutoSuperior Tecnico in Lisbon.

Recently, Cavaglia’s research focused on a number of issues in high-energy phenomenology andtheory.

6.1 Phenomenology – Particle Colliders

Braneworld scenarios lead to the revolutionary possibility that the quantum gravity scale could bewell below the Planck scale, even down to electroweak levels [1]. This raises the exciting prospectthat quantum gravity effects could be accessible via events at the TeV scale [2]. The adventof low-energy scale gravitational models offers a new chance to study gravitational events froma phenomenological point of view. In the context of the DOE involvement with CERN’s CMSdetector, it is of considerable interest to search for black hole systems at the TeV regime. TheLarge Hadron Collider may provide the first evidence of black hole production with missing ET

signature.Cavaglia wrote a Monte Carlo generator for strong gravitational events at CERN’s CMS detector.

The generator is linked to the PYTHIA Monte Carlo fragmentation code [3]. The events are injectedinto the OSCAR detector simulator (GEANT4-based CMS simulator [4]). OSCAR’s output isreconstructed and digitized with ORCA. Finally, ROOT tree Ntuples are created to analyze theevents. R. Godang (UM) runs the events and manages the detector response part of the simulations(OSCAR → ROOT). Up to date, he successfully generated 5000 black hole events through the CMSpackage software at Fermilab, using the Condor batch systems remotely.

Analysis of black hole events is in progress (see Fig. 16). The generator developed in Missis-sippi includes inelasticity effects, quantum corrections to semiclassical black hole evaporation andgravitational energy loss at formation. These features are essential to obtain a realistic detectorresponse and test different models of black hole formation and decay. This investigation will providean independent test of the main characteristics of the events, while showing new ways of discrim-inating between black holes and other exotic physics processes, or between alternative models ofblack hole formation and evolution. A complete analysis of black hole events at the CMS withdetector response will be the main priority for the next year, while working on improved versionsof the black hole generator.

The applications of this investigation are not limited to black hole formation at the Large HadronCollider. A simpler version of the black hole generator without hadronic structure can be used tosimulate gravitational events at lepton colliders. Preliminary results for the muon collider werepublished in Ref. [5]. Given that the Next Linear Collider energy is too low, and a muon collider isonly in the planning stage, a generator for black holes at lepton colliders is not a priority. However,

Most of the black holes produced at the LHC will have a mass of theorder of a few fundamental Planck mass. This plot does not take into account fragmentation and detectorresponse. (Cavaglia and Godang, preliminary result.)

it is worth noticing that the code developed in Mississippi is the first code of this kind to appear inthe literature.

Development and implementation of a hardware/software apparatus for simulations inclusive ofdetector response (OSCAR → ROOT) is also a powerful resource for additional high-energy tasks.The knowledge acquired by Cavaglia, Godang and collaborators can be transferred to differenttopics, according to the latest theoretical achievements.

6.2 Phenomenology – Cosmic Ray Detectors

Ultrahigh-energy cosmic rays (UHECRs) colliding with Earth’s atmosphere generate air showersthat can be detected with terrestrial or space observatories [6]. UHECRs have been observed withcollisional center-of-mass energies of hundreds of TeV. Therefore, they provide a natural means ofinvestigating high-energy particle physics.

In collaboration with a female graduate student (E.-J Ahn, University of Chicago) Cavagliainvestigated the observational signatures of gravitational events in UHECR air showers at the PierreAuger Observatory. Results are published in Ref. [7]. An advanced Monte Carlo code was writtento simulate black hole air shower detection in fluorescence telescopes and ground arrays [8]. TheMonte Carlo includes many theoretical features which recently appeared in the literature. Theseeffects are expected to reduce the multiplicity of the black hole decay, thus modifying the air showersignatures of previous studies [9]. It was found that black hole air showers tend to rise faster andhave larger muon contents than standard model air showers. A black hole air shower is similar to ahadronic air shower occurring at a greater depth in the atmosphere. Distinguishing standard modeland black hole air showers at the Pierre Auger Observatory might be possible if enough statisticsis gathered. The most promising way is to measure the air shower maximum with a fluorescence

telescope and count muons at the ground (Fig. 17). No tau double bang signature [10] is likely tobe observed in black hole events. However, further study is required to reach a definite conclusion.

Simulations of strong gravitational effects in cosmic ray detectors complement the particlephysics effort, providing essential information on the phenomenology of braneworld models andlow-scale gravity. Cavaglia plans to continue the analysis of strong gravitational effects at cosmicrays observatories by extending current results to other exotic phenomena, such as string balls,branes and string excitations [14].

6.3 Theory

Small-scale quantum effects on black hole thermodynamics were investigated by Cavaglia and B.Bolen (UM, now Western Kentucky University) [11]. The derivation of Hawking temperature viathe uncertainty principle was extended to the (anti-)de Sitter spacetime. The thermodynamics ofthe Schwarzschild-(anti-)de Sitter black hole is obtained from the generalized uncertainty principleof string theory and non-commutative geometry.

In the context of astroparticle physics, Cavaglia investigated graviton production in braneworldmodels with M. Gasperini and G. de Risi (University of Bari) [12]. The cosmological amplificationof tensor perturbations with massless gravitons localized on a Kasner-like brane were discussed.In contrast to de Sitter models of brane inflation, it was found that there is no mass gap in thespectrum and no enhancement for massless modes at high curvature. The massive modes can beamplified even during inflation and in the absence of any mode-mixing effect.

In collaboration with V. Cardoso (Washington University, now UM) and E. Berti (Washing-ton University), Cavaglia investigated theoretical issues on black hole formation in super-Planckianparticle collisions [13]. This study was motivated by recent theoretical advances in the under-

27

standing of gravitational radiation emission in relativistic particle scattering (a topic related to thephenomenology investigations described above). The main purpose of this work was to comparedifferent methods for the estimate of the total gravitational energy emitted in this process. Upto now, black hole formation has mainly been studied using an apparent horizon search technique.This approach yields only an upper bound on the gravitational energy emitted during black hole for-mation. Alternative calculations based on instantaneous collisions of point particles and black holeperturbation theory suggest that the apparent horizon method may overestimate the gravitationalemission.

In addition to phenomenology tasks, the investigation of the latter topic will be continued.Under the supervision of Cavaglia, a UM student (A. Roy) is studying the effect of EM chargeon the formation of the apparent horizon. Computation of the graviton greybody factor for D-dimensional black holes is in progress (Cardoso, Gualtieri and Cavaglia). These results will beapplied to specific models of black holes formation in super-Planckian collisions.
