Instructions

GenXSecAnalyzer can be used to compute the cross section correctly in the MC production or for the physics analysis (on an existing MC sample, in MINIAODSIM format file)

Step 1: Set up CMSSW version

The CMSSW release must not predate the release that was used in writing the input files. For the example input files here, CMSSW 13_0_13 was used.

cmsrel CMSSW_13_0_13
cd CMSSW_13_0_13/src
cmsenv

Step 2: Clone the repository

git clone [email protected]:Ksavva1021/GenXSecAnalyzer.git
cd GenXSecAnalyzer

Step 3: Produce the input .txt files

We utilise dasgoclient to get the list of files in the sample of interest.

dasgoclient -query="file dataset=/GluGluHJJto2TauUncorrelatedDecay_CP-mix_M-125_CP5_13p6TeV_powheg-minlo-pythia
8/Run3Summer22MiniAODv4-130X_mcRun3_2022_realistic_v5-v2/MINIAODSIM" &> GluGluHJJto2TauUncorrelatedDecay_CP-mix.txt

Step 4: Run ana.py to compute cross-sections/filter-efficiencies

Note: You can set the maxEvents to your preference: -1 $\rightarrow$ whole file

cmsRun ana_new.py inputFileList=GluGluHJJto2TauUncorrelatedDecay_CP-odd.txt maxEvents=-1
