“This large unit has produced some truly remarkable achievements and some of its groups are at the leading edge of European Physics Research, acting on and contributing to hot current issues. About half of the members are working in elementary particle physics.”...“All the topics under investigation are of great relevance and on the cutting edge of particle theory, e.g. SUSY and CP violation, neutrino masses and neutrino mixing, baryogenisis through leptogenisis. Topics that combine particle and astrophysics concern dark matter, dark energy and inflation. But also data from B-factories are analysed.”....

International NetworksCFTP Participates in three EUROPEAN NETWORKS, which include some of the most prestigious Universities and Research Institutes in Europe.

The competition among the various Universities/Research Institutes is very strong, so the fact that we are part of 3 NETWORKS, reflects the recognition of CFTP in the international context as a center of excelenceand the leader Theoretical Particle Physics in Portugal.

• Tools and Precision Calculations for Physics Discoveries at Colliders (17 institutions including the universities of Durham, Paris Sud, INFN, DESY, Max-Planck-Institut, Brookhaven National Lab, KEK, CERN)

• Quest for Unification (13 institutions, including Saclay, INFN, Oxford U., Valencia U., CERN and Stanford U.)• EtaMesonNet, in the context of HPI3 Hadron Physics IntegratedInfra-structure Initiative) of the VI Framework Project (31 institutions, including London U.C., Hamburg U., Helsinki HIP, Uppsala U., Valência U., INFN)

NETWORKS:

Important International Working GroupsWe have also collaborated in several International Working Groups contributing to the preparation of the final reports:


Cooperation with National Research Institutes

CFTP, LIP (particle phys. experimentalists) and CENTRA (astrophysics), have joined efforts and created the PASC initiative.

We want to increase the offer of courses and post-graduate studies of Physics Engineering in Particle, Astrophysics and Cosmology, at the level of Master of Science (2nd Bologna cycle) and Ph.D. (3rd Bolongna cycle).

PASC is going to intensify the interaction of the 3 centers.

PASC has about one 100 researchers with PhD.

The 3 centers maintain also intense international collaboration with the world's leading scientific institutions in these areas, such as CERN and ESO as well as with a great number of European, American and Japanese universities, participating also in important Networks financed by the European Union.

Successes of PhD students and Post Docs

CFTP has given special importance to the training of Ph.D graduate

Students and Post-Docs.

Perhaps the most objective way of judging the quality of a program of training Ph.D Students and Post-Docs is by investigating their carreers after they leave CFTP.

CFTP program for training Ph.D Students and Post-Docs

CFTP is proud that our Ph.D students and Post-Docs have done very well after leaving CFTP.

Research in Particle Physics Anticipating a New Golden Age

Frank Wilczek (Nobel Laureate, MIT)

“The Standard Model of Fundamental Interactions is remarkably successful, but it leaves an unfinished agenda.”

“Several major questions seem ripe for exploration in the near future.”

“I anticipate that the coming decade will be a golden age of discovery in Fundamental Physics.”


1. What is the origin of Electroweak Symmetry breaking?2. How to understand the origin of Mass and the pattern of

Fermion Masses and Mixings, including Neutrinos?3. Supersymmetry: if present at what scale will it be

manifest?4. How to generate the observed Baryon Asymmetry of the

Universe?5. How to solve QCD?6. What is Dark Matter?7. What is Dark Energy?8. Quantum Gravity: an old fundamental question.9. Are there Extra Dimensions?10.What else is out there?

Some of the Fundamental open questions in Particle Physics


Question 1: What is the origin of Electroweak Symmetry breaking?

Examples of CFTP work related to the above question:

Research work of CFTP

The work of CFTP covers most of the 10 questions listed by Frank Wilczek.

Most plausible answer: Spontaneous Symmetry Breaking through the Higgs mechanism

Study of Multi-Higgs systems, with emphasis on the structure of the vacuum.

Study of Weak-Basis invariants in the Higgs sector:

Question 2: How to understand the origin of Mass and the pattern of Fermion Masses and Mixings, including

Neutrinos?


This is one of the most fundamental questions in Particle Physics which has become even more intricate since the discovery of Neutrino masses and mixings.

Main point: Gauge invariance does not constrain the flavour structure of Yukawa interactions. As a result, most of the free parameteres of the SM consist of fermion masses and mixing.

Luís Lavoura M. N. RebeloJoaquim Silva-MarcosRicardo Gonzalez-FelipeGustavo C. BrancoPaulo A. ParadaJoão Pulido Jorge C. RomãoDavid Emmanuel-CostaAna M. TeixeiraIvo Medeiros VarzielasMiguel R. Nebot GómezA. Villanova del MoralMaria A. Tórtola BaixauliPavel Fileviez PerezJ. A. Aguilar-Saavedra Gregory MoreauBhag C. ChauhanMario GomezSolveig Skadhauge

There has been in CFTP a lot of work on this question using the introduction of Family symmetries and/or the use of Weak-Basis invariants. Some of this work has had a great impact in the literature (see the list of CFTP papers with 100 or more citations)

Counting of parameters:

Quark sector:6 quark masses + 3 mixing angles + 1 cp violating phase= 10

Lepton sector:6 charged lepton masses + 3 mixing angles + 3 cp violating phases = 12

So altogether we have 22 free parameters in the fermion sector!!!


Question 3 (and 8): Supersymmetry, if present at what scale will it be manifest?Although there is not yet direct experimental evidence forSUSY, there are many theoretical arguments indicating that SUSY might be of relevance for physics below the 1 TeV scale.•The most commonly invoked theoretical arguments for SUSY are:Interrelates matter fields (leptons and quarks) with force fields (gaugeand/or Higgs bosons).

•As local SUSY implies gravity (supergravity) it could provide a way tounify gravity with the other interactions.

•As SUSY and supergravity have fewer divergences than conventional fieldtheories, the hope is that it could provide a consistent (finite) quantumgravity theory.

•SUSY can help to understand the mass problem, in particular solve thenaturalness problem (and in some models even the hierarchy problem) ifSUSY particles have masses ≤ O(1TeV).•Unification of Gauge Coupling better in SUSY GUT’s.

Question 4: How to generate the observed Baryon Asymmetry of the Universe?


M. N. RebeloRicardo Gonzalez-FelipeGustavo C. BrancoJoaquim Silva-MarcosDavid Emmanuel-CostaAna M. TeixeiraFilipe Joaquim

We have addressed this question in the framework of Baryogenesis through Leptogenesis, where first a Lepton Asymmetry is created through the CP violating decays of the Heavy Neutrinos and then this Lepton Asymmetry is converted into a Baryon Asymmetry throughB+L violating but B-L conserving Spharelon processes. In our work, we paid special attention to the possible connection between the size of the Lepton Asymmetry generated and low energy parameteres in the Leptonic sector.

This work has had significant impact in the in the literature. (see the list of CFTP papers with more than 100 citations)

Questions 6, 7:

What is Dark Matter?What is Dark Energy?

Question 9: Are there Extra Dimensions?


Joaquim Silva-MarcosGregory MoreauM. N. RebeloGustavo C. Branco

Will we be able to see any signature of Extra Dimensions in the LHC? And How?

We have addressed this question and constructed models with Extra Dimensions, where intrinsic geometrical mechanisms can explain the origin of the large mass hierarchies among the Standard Model fermions.


Question 10: What else is out there?


Of course this is the most exciting of all Questions.

Will experiment (not only LHC) give us some real surprises?
