Short description

CMG is a general analysis tool developed and maintained by CMS. Is being used by many analysis. CMG provides several common tools and functionallities and each analysis developing their code using those tools. The present code is dedicated to B physics in general and in particular Rk analysis. For the general recipe, follow these instructions.

Run (working examples)

nanopy.py test run_RK_fromNanoAOD_cfg.py -N 10000 -o kmumu -o jpsi -o mc -o filterSample=BuToKJpsiMuMu_test -o dimuon # MC
nanopy.py test run_RK_fromNanoAOD_cfg.py -N 10000 -o kmumu -o jpsi -o data -o filterSample=Charmonium_test # data

Basic code

NanoAOD ntuples definition: CMGTools/RootTools/python/samples/samples_13TeV_BParkingData_NanoAOD.py
Module sequence and structure: CMGTools/RKAnalysis/python/tools/nanoAOD/BParking_modules.py
Configuration: CMGTools/RKAnalysis/cfg/run_RK_fromNanoAOD_cfg.py
Plotting: CMGTools/RKAnalysis/python/plotter/experimental/plotter2.py

Usage

Skimming NanoAOD

Main code (ie modules to run and running order) defined in BParking_modules.py
Local run: nanopy.py <folder>  run_RK_fromNanoAOD_cfg.py -N <evts per dataset> -o xxx=yyy
Batch run: nanopy_batch.py -o <localOutput> -r /eos/space/<remoteOutput> -b 'run_condor_simple.sh -t 1200' run_RK_fromNanoAOD_cfg.py --option <xxx>=<yyy>
Options:
- mc to run on MC
- data to run on data
- njobs number of chuncks to create
- kmumu to run on B -> Kmumu
- kee to run on B -> Kee
- kstarmumu to run on B ->K*mumu
- onlyPFe runs kee channel only with 2PF
- onlyLowPtAndPFe runs kee channel only with 1PF & 1 Low pT
- jpsi when run on mc (only in mc used) requires e to come from Jpsi mother
- psi2s same for excited jpsi
- test to take one file per dataset
- single for single threaded run. this needs "--single"

Proxy error

In the following error, during submission in condor, is encountered:

Submitting job(s)ERROR: use_x509userproxy=/afs/cern.ch/work/r/ratramon/CMSSW_10_4_0/src/CMGTools/RKAnalysis/cfg/X509_USER_PROXY is invalid, must eval to a boolean

go to PhysicsTools/HeppyCore/scripts and comment out the line use_x509userproxy = \$ENV(X509_USER_PROXY) from both run_condor.sh and run_condor_simple.sh
then re-compile
