TRANSCRIPT
The Standard Model (again)
Particles grouped into generations by mass
Higgs field with non-zero VEV causes EWSB -> mass
Higgs boson is the particle associated with this field
Run I vs. Run II
Increase in center-of-mass energy->1.96TeV
Increase in number of bunches, decrease in spacing of bunches
Much higher luminosity (Hopefully) enough for
Higgs boson detection
Higgs Decay Modes
bb channel dominant up to M=135GeV
Z boson decays into two muons less frequent, but also cleaner channel
Importance of the Results
NN achieves better signal/background discrimination than cuts on Mjj alone
NN analysis gives better signal significance than conventional analysis
Integrated luminosity required for Higgs detection reduced 40-70%
Not too shabby
