H → ZZ → 4L Sub Pages

• GlobeHtoZZSamples - Data Set information can be found on this page
• GlobeHtoZZCstep - Current status of cstepped files
• GlobeHtoZZVars? - Variables of relevance to the H → ZZ → 4L analysis
• GlobeHZZInitialPlots - initial plots July 24th, 2008
• HZZ status plots 2 Oct. 2008:

First example to look at:

Read it and get version GLOBE_011
cvs co -r GLOBE_011 -d globe UserCode/Mpieri/globe
You don't need to checkout Analyzers and do anything with them for now, the include files are ok for the root trees provided for the example.

Then follow the examples for H to ZZ described in Hzz_scripts/00README.txt
http://uaf-1.t2.ucsd.edu/viewvc/UserCode/Mpieri/globe/Hzz_scripts/00README.txt?view=markup

If you have problems getting the code from cvs you can ask Elizabeth or Sean

Note that at the beginning one only needs to mdify the few methods in the Hzz directory and the files in the Hzz_scripts directory
The example of the genereted and reconstructed electrons and muons is meant to be an example, it is incomplete and may not be completely correct.
As a first exercise one can implement the things written below in the reduction (R-step) except those that cannot be done, for example the matching gen-rec can currently only be done by DeltaR no tracker hits.

H → ZZ → 4L

• List of Leptons
  • n_l > 4
  • isolation
    • tracker (done)
    • ECAL
  • P^μ
  • lepton id
  • η
  • φ
  • MC Truth
    • matching by hits to tracking particles (50%)
    • trackless electron (ΔR < 0.3 ?? , or Energy Match )
    • fake leptons tree tracing
• 4L ≡ e^±e^±μ^±μ^±
  • [ (eμ), (e⁺e⁺) ] for control
• FSR photon in isolation study?
• Recoed Brem Conversion?
• 4 Lepton Hypothesis
  • MET
    • how is this calculated
    • same as in top group
• Gluon Fusion vs. VBF
  • how to reco these jets?
  • # of Jets
    • E_jet > 5 GeV?
