Variables in the ntuple

The nominal_Loose ntuple has more than 300 different variables, recorded for each event. Below is an initial list of basic variables to look at, mostly related to the hadronic jets, electrons, muons and missing energy, and their respective properties.

 - Mll
 - pTll
 - HTall
 - nBTags_MV2c10_60 (70/77/85)
 - nJets
 - nJets_Pt40
 - nElectrons
 - nMuons
 - nTaus (hadronic taus reconstructed)
 - truth_HDecay
 - mcChannelNumber (DSID)
 - truth_top_dilep_filter
 - jet_pt[], jet_eta[], jet_phi[], jet_e[], jet_mv2c10[], jet_jvt[]
 - el_pt[] + eta/phi/e/charge;
 - mu_pt[] + eta/phi/e/charge;
 - met_met, met_phi
 

Selecting a specific Higgs decay mode (truth_HDecay)

In the simulated event samples (as opposed to the real data samples) if a Higgs particle is generated its decay is recorded via the truth_HDecay variable in the ntuple. This is an integer between 0 and 8:
