Getting started

Data sample

see CSA07Physics (photon + jet -> gumbo) in DBS look for *PD*skim*photonjets*

IsolatedTauTagInfo used in charged Higgs analysis, see tauTag.cc http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/CMSSW/HiggsAnalysis/HeavyChHiggsToTauNu/src/tauTag.cc?revision=1.5&view=markup

This collection is in AOD: https://twiki.cern.ch/twiki/bin/view/CMS/SWGuideDataFormatRecoTauTag

Default parameters for this collection http://cmslxr.fnal.gov/lxr/source/RecoTauTag/ConeIsolation/data/coneIsolationTauJetTags.cfi?v=CMSSW_1_6_7 while ptmin > 20 for hard taus

Analysis

• build the starter kit: https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookAnalysisStarterKit
  • as of Apr 8, remove scratch in front of PATLayer1Output.root in StarterKitDemo.cfg
  • as of Apr 8, comment es_prefer MCJetCorrectorIcone5 = MCJetCorrectionService {} in PatAlgos/data/PATJetMETCorrections.cff
• prepare CRAB environment

  ssh lxplus
  cd ~/scratch1/StarterKit/CMSSW_1_6_10/src/PhysicsTools/StarterKit/test
  source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.csh
  eval `scramv1 runtime -csh`
  source /afs/cern.ch/cms/ccs/wm/scripts/Crab/crab.csh

• prepare crab.cfg (the base from crab.cfg link of the dbs page - available when it works - mod's for the output file name and the output SE)

• run over the sample

  crab -create
  crab -submit 
  crab -status
  crab -getoutput (not needed if written directly to castor)
  

• some files in castor: /castor/cern.ch/user/k/kati/crab/test/
• look for photon, jet, tau (with leading track > 20)
• match jet and tau
