TreeWriter to build a ROOT tree from MiniAOD. Photon Cut- and MVA-IDs are computed.

Run the TreeWriter

• locally

voms-proxy-init -voms cms
cmsRun TreeWriter/python/runTreeWriter.py

• on the Grid using CRAB3

. /cvmfs/cms.cern.ch/crab3/crab.sh
cd crab

for a single dataset

crab submit -c crabConfig.py

for all datasets

python2 crabConfig.py

Configure

in the python config, set

• HT_cut: minimum HT
• photon_pT_cut: minimum leading-photon pT

Objects

Photons

• official cut-based ID for Spring16 and Spring15 are stored TWiki
• all photons are used. boolean flags for: loose/medium/tight

Jets

• ak4PFJetsCHS
• all jets are used
• boolean flag for: loose
• boolean flags for whether a loose electron/photon is found within dR<0.4

Muons

• fulfilling loose id
• tight id boolean flag
• relative isolation is stored

Electrons

• fulfilling "veto" id
• boolean flags for loose/medium/tight
• recipes on TWiki

Generated Particles

• genJets collection is stored (= full slimmedGenJets)
• gen[Electrons|Photons]: status=1, pT>30
• Decay products (daughters) of W bosons
