Matrix Element Inputs in CMS2

• This page documents the procedure to generate the this input Smurf Ntuple and the utility histograms that are needed to do the ME calculations. The code can be browsed here.
• Please refer to the instructions here for the ME calculation instruction.*

• Instructions
  • Getting the looper code from CVS (here I assume that you have already set up your favorite CMSSW release)

       cvs co -d Smurf/ UserCode/Smurf
       cvs co -d CMS2/NtupleMacros/CORE UserCode/JRibnik/CMS2/NtupleMacros/CORE
       cd CMS2/NtupleMacros/CORE
       cvs up -r WW2010 CMS2.h CMS2.cc
       cd ../../../
       cvs co  -d CMS2/NtupleMacros/HWWME UserCode/JRibnik/CMS2/NtupleMacros/HWWME
       cvs co -d CMS2/NtupleMacros/Tools UserCode/JRibnik/CMS2/NtupleMacros/Tools
       

  • You need to create two soft links, one pointing to the ntuple location "data" and one pointing to "CORE"

       cd CMS2/NtupleMacros/HWWME
       ln -s /tas/cms2 data
       ln -s ../CORE CORE
       

  • Run script doAll.C to produce the input files for the ME calculations,

         root -l doAll.C
        

  • This looper creates a smurf ntuple for each process and one utility root file called either Util_HWW.root or for Util_HZZ.root, which contains the lepton efficiency, boost and fake rate related histograms.

• Files for the SmurfV6 selections using 41X
  • Location: /smurf/yygao/data/EPS/auxilliar/
