MC production

Visit this directory.

Ntuple production

source /cvmfs/cms.cern.ch/cmsset_default.sh
cd Entanglement/CMSSW_12_4_8/src/TauAnalysis/Entanglement
./test/produceNtuples.py -v 2023Oct06_wSmearing -s dy_lo_pythia8 -j local # or -j cluster

Execute make command as instructed in terminal window

Run the analysis code on the Ntuples

source /cvmfs/cms.cern.ch/cmsset_default.sh
cd Entanglement/CMSSW_12_4_8/src/TauAnalysis/Entanglement
# run inclusive measurement + scan in |cos(theta)| on all decay modes (except had_had) on the cluster
./test/analyzeNtuples.py -v 2023Oct22        -V 2023Oct06_wSmearing -s dy_lo_pythia8_ext -j cluster \
  -M inclusive scan
# run inclusive measurement + scan in |cos(theta)| on fully hadronic decay modes (had_had) locally
./test/analyzeNtuples.py -v 2023Oct22_hadHad -V 2023Oct06_wSmearing -s dy_lo_pythia8_ext -j local   \
  -M inclusive scan -d had_had
