NanoAOD producer customized for BParking analyses

The focus is on RK/K*/phi analyses.

Recipe

This recipe is for 12_4_X. The original recipe for 10_2_X can be found here.

Getting started

scram list CMSSW
cmsrel CMSSW_12_4_8
cd CMSSW_12_4_8/src
cmsenv

Add modifications needed to use post-fit quantities for electrons

git cms-merge-topic -u DiElectronX:GsfTransientTracks_124X # unsafe checkout (no checkdeps), but suggested here

Add modifications to KinematicParticleVertexFitter

git cms-merge-topic -u DiElectronX:fixKinParticleVtxFitter_124X # unsafe checkout (no checkdeps), but suggested here

Add the BParkingNano package

git clone git@github.com:DiElectronX/BParkingNANO.git ./PhysicsTools
git cms-merge-topic -u DiElectronX:NanoAOD_131X

Build and run on a test file

cd $CMSSW_BASE/src/
scram b -j 8
cd PhysicsTools/BParkingNano/test
cmsRun run_nano_cfg.py        # by default, runs over Run 3 data
cmsRun run_nano_cfg.py isMC=1 # runs over MC for 2022

Submit CRAB jobs to process Run 3 data and 2022 MC

cd $CMSSW_BASE/src/PhysicsTools/BParkingNano/production
python3 submit_on_crab.py

Provenance and branches

• This repo is forked from https://github.com/CMSBParking/BParkingNANO
• The fork was made at revision https://github.com/CMSBParking/BParkingNANO/tree/b9bcad0b9b
• This revision is tagged as https://github.com/DiElectronX/BParkingNANO/tree/from-BParkingNANO
  • Tag also available as https://github.com/CMSBParking/BParkingNANO/tree/from-BParkingNANO

Default branches:

• The default branch in CMSBParking is https://github.com/CMSBParking/BParkingNANO/tree/master
• The default branch in DiElectronX is https://github.com/DiElectronX/BParkingNANO/tree/main

The default branch has been renamed for two reasons:

1. To promote more inclusive terminology, as per the GitHub guidelines
2. To clearly differentiate between the different development thread of the two repositories, namely:
   • CMSBParking/BParkingNANO:master targets the CMSSW development cycle CMSSW_10_2_X
   • DiElectronX/BParkingNANO:main targets the CMSSW development cycle CMSSW_12_4_X

Further, two additional branches have been produced based on the revision above:

• CMSBParking/BParkingNANO:CMSSW_10_2_X and CMSBParking/BParkingNANO:CMSSW_12_4_X
• DiElectronX/BParkingNANO:CMSSW_10_2_X and DiElectronX/BParkingNANO:CMSSW_12_4_X

which may be of use. For example:

• CMSSW_10_2_X developments in CMSBParking/BParkingNANO should be merged into the master (and CMSSW_10_2_X) branch
• CMSSW_12_4_X developments in CMSBParking/BParkingNANO should be merged into the CMSSW_12_4_X branch
• CMSSW_10_2_X developments in DiElectronX/BParkingNANO should be merged into the CMSSW_10_2_X branch
• CMSSW_12_4_X developments in DiElectronX/BParkingNANO should be merged into the main (and CMSSW_12_4_X) branch
