Introduction

This twiki page is for cut-flow comparison on 20.7 data and MC. The yields are corresponding to the v23 ntuples on:

root://eospublic.cern.ch//eos/escience/UniTexas/HSG8/multileptons_ntuple_run2/25ns_v23/version_1/Nominal/34336*.root # ttH Pythia8

The weight for MC samples is given by

SCALE_weight*mcWeightOrg*pileupEventWeight_090*MV2c10_70_EventWeight
*((dilep_type||trilep_type)*lepSFObjTight*lepSFTrigTight+(quadlep_type>0)*lepSFObjLoose*lepSFTrigLoose)
*tauSFTight*JVT_EventWeight*SherpaNJetWeight

multiplied by 36470 for an integrated luminosity of 36.5 fb⁻¹ .
The SCALE_weight contains the cross section and total number of events. It’s calculated with GFW2 using the total sum over all entries of the branch “totalEventsWeighted” in the tree “sumWeights”. The cross sections are taken from TopDataPreparation. If you want to check the SCALE_weight (=5.258717e-08) for sample 341177 with cross section 0.0536 pb:

root -l -b 341177.root
sumWeights->Draw("1>>h","totalEventsWeighted","texth")
0.0536/h->Integral()

The old cut-flow on v19 group ntuples you find on TTHtoLeptonsCutflow207?rev=20.
