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

Instruction

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

   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
   

• 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
   

• Compile code by running gmake

• Make the WW or ZZ util files by running make commands..

make ww
make zz

• 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/
