BoostedTTH

CMSSW tools for analyzing TTH events with boosted objects

Build Status

Installation

Follow These Steps:

# setup environment
export SCRAM_ARCH="slc6_amd64_gcc630"
export CMSSW_VERSION="CMSSW_9_4_9"


# create new CMSSW environment
scram project $CMSSW_VERSION
cd $CMSSW_VERSION/src
export CMSSWSRCDIR="$( pwd )"
eval `scramv1 runtime -sh`

git cms-merge-topic cms-egamma:EgammaPostRecoTools_940 #just adds in an extra file to have a setup function to make things easier
#git cms-merge-topic cms-egamma:Egamma80XMiniAODV2_946 #adds the c++ changes necessary to enable 2016 scale & smearing corrections (is loaded per default)

Overview

BoostedObjects contains the classes needed for subjet-analysis. They associate fat jets with the corresponding filtered objects.

BoostedProduces contains the tools used to run the HEPTopTagger and SubjetFilterJet algorithm on MiniAOD and add the output as the above collections.

BoostedAnalyzer can be used to analyze MiniAOD files. The plugin itself takes care of objectselections and stores the objects in InputCollections. Different event selection can be used in this step, too. The inputcollections can be analyzed with a TreeWriter that can load different Processors. Every processor writes a certain class of output variables in a flat TTree.
