llp_ntupler

Long Lived Particle Ntupler based on AOD

Setup CMSSW & clone the ntuples:

# Done once to setup environment
cmsrel CMSSW_10_6_4_patch1 
cd CMSSW_10_6_4_patch1/src
git clone git@github.com:cms-lpc-llp/JetToolbox.git  JMEAnalysis/JetToolbox
cd JMEAnalysis/JetToolbox; git checkout jetToolbox_91X; cd -;
git clone git@github.com:cms-lpc-llp/llp_ntupler.git cms_lpc_llp/llp_ntupler
cd cms_lpc_llp/llp_ntupler; git checkout HeavyIonRun2; cd -;
scram b
cmsenv
# Run the ntuples
cmsRun python/jetNtupler_MC_AOD.py

Variables to check before running nTupler:

• isQCD: False if running signals, True if running QCD
  • Matching is done differently for QCD
• isFourJet: False for glueball model; True for fourjet
  • Difference is LLP particle IDs are different in the two models
• readGenVertexTime: False for glueball model; True for fourjet
  • Difference is glueball model used 2016 condition, doesn't have genVertexTime info for now. (will have them when the new samples are ready)
• Output file name:

process.TFileService = cms.Service("TFileService",
        fileName = cms.string('input.root'),
    closeFileFast = cms.untracked.bool(True)
)

• Input file name:

process.source = cms.Source("PoolSource",
    fileNames = cms.untracked.vstring('output.root'),
)

AODSIM Location

They are all on Caltech tier2: (should be accessible through xrootd) /mnt/hadoop/store/user/christiw/RunII2016/ The different directories are different h production mode

• ggh: ppTohToSS1SS2_SS1Tobb_SS2Toveve_MC_prod
• vbfh: ppTohjjToSS1SS2_SS1Tobb_SS2Toveve_MC_prod
• wh: ppTohwToSS1SS2_SS1Tobb_SS2Toveve_MC_prod
• zh: ppTohwToSS1SS2_SS1Tobb_SS2Toveve_MC_prod
• ggh with ISR: ppTohToSS1SS2_SS1Tobb_SS2Toveve-ppTojhToSS1SS2_SS1Tobb_SS2Toveve_MC_prod
• There are a few mass points / ctau points for each production modes, some production modes only have one point
• Once in a particular mass/ctau directory, AODSIM is in the directory that ends with *DR-AODSIM_CaltechT2/
• eg: the four ROOT files in /mnt/hadoop/store/user/christiw/RunII2016/ppTohToSS1SS2_SS1Tobb_SS2Toveve_MC_prod/ppTohToSS1SS2_SS1Tobb_SS2Toveve_run_m10_pl10000_ev10000/crab_CMSSW_8_0_31_ppTohToSS1SS2_SS1Tobb_SS2Toveve_run_m10_pl10000_ev10000_DR-AODSIM_CaltechT2/19012\ 0_072347/0000/ are AODSIM
