I am studying jet performance, particularly for the Higgs to diphoton channel. - Which jet reconstruction algorithm (AntiKt4EMTopo/PFlow) is best suited for our samples? - In whcih situations do the jet energy scale and resolution performance suffer? Can they be improved? The work-in-progress code is called HGamJetStudy, a RootCore package for two studies: 1. ''MCJES'' : Monte-Carlo based jet energy scale & resolution for general samples. 2. ''JetDiphotonScale'' : (new) Look at "response" of jet to diphoton in Higgs samples. The outputs are used to give us results (pretty plots): 1. ``MCJES -> plotJES``: JES results 2. ``MCJES -> plotJER``: JER results 3. ``JetDiphotonScale -> ???``: (to be done) Full code and instructions are hosted on GitLab: My working direcctory is setup on CERN AFS: <code> /afs/cern.ch/work/t/tapark/public/AnalysisBase-2.4.28 </code> (to be moved to EOS in the future) ''AnalysisBase-X'': code repository for the work. ''xAOD'': local copies of some sample files for testing. ''MCJES'': results for this study. ''JetDiphoton'': results for this study.
