Framework for tau analysis using NanoAOD at CMS. Three main packages are
PicoProducer: Tools to process nanoAOD and make custom analysis ntuples.Plotter: Tools for further analysis, auxiliary measurements, validation and plotting. [Under development.]Fitter: Tools for measurements and fits in combine. [Under development.]
First, setup a CMSSW release, for example,
export CMSSW=CMSSW_10_6_13
export SCRAM_ARCH=slc7_amd64_gcc700
cmsrel $CMSSW
cd $CMSSW/src
cmsenv
Which CMSSW version should matter for post-processing of nanoAOD,
but if you like to use Combine in the same repository,
it is better to use at least the recommended version.
Then, install TauFW:
cd $CMSSW_BASE/src/
git clone https://github.com/cms-tau-pog/TauFW TauFW
scram b -j4
With each new session, do
export SCRAM_ARCH=slc7_amd64_gcc700
cd $CMSSW/src
cmsenv
If you want to process nanoAOD using PicoProducer, install NanoAODTools:
cd $CMSSW_BASE/src/
git clone https://github.com/cms-nanoAOD/nanoAOD-tools.git PhysicsTools/NanoAODTools
scram b -j4
If you want to use tau ID SF, please install TauIDSFs tool:
cd $CMSSW_BASE/src
git clone https://github.com/cms-tau-pog/TauIDSFs TauPOG/TauIDSFs
cmsenv
scram b -j4
If you want to use the Combine tools in Fitter, install
Combine,
cd $CMSSW_BASE/src
git clone https://github.com/cms-analysis/HiggsAnalysis-CombinedLimit.git HiggsAnalysis/CombinedLimit
cd HiggsAnalysis/CombinedLimit
git fetch origin
git checkout v8.1.0
and then CombineHarvester,
cd $CMSSW_BASE/src
git clone https://github.com/cms-analysis/CombineHarvester.git CombineHarvester
