Skimmed_background

This is the background dataset used in the analysis

Skimming script inCBOnlySemileptonicFilter/selectBackground (leptons were balanced)

3 files (in results):

• TTbarSemileptonic_Nocb_LeptFromTbar.root

• TTbarSemileptonic_Nocb_LeptFromT.root

• TTbarSemileptonic_Nocb.root (the two above merged)

Dataset obtained skimming (using RDataframe) NON cb events from the files (in input_files):

• input_files/leptonFromT.root /store/mc/RunIISummer20UL18NanoAODv9/TTJets_SingleLeptFromT_TuneCP5_13TeV-madgraphMLM-pythia8/NANOAODSIM/106X_upgrade2018_realistic_v16_L1v1-v1/2520000/FDB5DCAF-D98E-9C4D-9057-9E11BBEA6970.root

Generated signal

Dataset generated using FULLSIM (scripts in generateCbEvents )

This is the signal dataset used for the analysis

3 files:

• TTbarSemileptonic_cbOnlyFromT_pruned.root

• TTbarSemileptonic_cbOnlyFromTbar_pruned.root

• TTbarSemileptonic_cbOnly_pruned_optimized.root

pruned = ParameterSets tree removed (It was weirdly huge and useless)

optimized = merging optimizing the tree basket size

Muons

Dataset generated skimming the signal and the background dataset with some cuts on muon events

file:

• TTbarSemileptonic_Nocb_MuonSelection.root

• TTbarSemileptonic_cbOnly_pruned_optimized_MuonSelection.root

In them there is only the Events TTree

Not used in the analysis (bad folder)

Dataset used only in the first stage of the LHE analysis. Not used for anything else

  Observation: cb events have always the same lepton

Skimming scripts in CBOnlySemileptonicFilter/NANOAODTools

3 files:

• cbFromT_SingleLeptFromTbar.root

• cbFromTbar_SingleLeptFromT.root

• TTbar_Semileptonic_cbOnly.root (the two above merged)

Dataset obtained skimming (using NanoAODTools on CRAB) cb events from the datasets:

• cbFromT_SingleLeptFromTbar: /TTJets_SingleLeptFromTbar_TuneCP5_13TeV-madgraphMLM-pythia8/RunIISummer20UL18NanoAODv9-106X_upgrade2018_realistic_v16_L1v1-v1/NANOAODSIM
