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)
    [CRAB]
    
    jobtype                 = cmssw
    scheduler               = glitecoll

    datasetpath             = /CSA07AllEvents/CMSSW_1_6_7-CSA07-Gumbo-B1-PDAllEvents-Skims1-photonjets_AODSIM/USER
    pset                    = StarterKitDemo.cfg
    total_number_of_events  = 1000
    events_per_job          = 100
    output_file             = PATLayer1Output.root

    return_data = 0
    copy_data = 1
    storage_element = srm.cern.ch
    storage_path = /srm/managerv1?SFN=/castor/cern.ch/user/k/kati/crab/test
    
    use_central_bossDB = 0
    use_boss_rt = 0
    
    [EDG]
    rb                      = CERN
    proxy_server            = myproxy.cern.ch

    lfc_host                = lfc-cms-test.cern.ch
    lfc_home                = /grid/cms
  • 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
