Analysis

Analysis framework for cms top quark charge asymmetry

This repository contains software for performing the charge asymmetry analysis in CMS. There are two main directories:

• Genesis
  • Originally developed here as ttbarAC_skim.
  • This framework generates flat ntuples from MiniAOD.
• CyMiniAna
  • Originally developed here.
  • This is the local analysis framework that processes flat ntuples and produces TTrees/histograms/efficiencies/etc.

Additionally, submodules for hepPlotter, asimov, and cheetah are also included in this project.

Getting Started

Create a CMSSW environment:

cmsrel CMSSW_9_4_4
cd CMSSW_9_4_4/src
cmsenv

Check out necessary packages (including this one):

### 2016 ###
# VID (Electron ID)
git cms-addpkg RecoEgamma/ElectronIdentification
git cms-addpkg PhysicsTools/SelectorUtils

### 2017 ###
# Updated Egamma IDs (creates RecoEgamma and PhysicsTools directories)
# https://twiki.cern.ch/twiki/bin/view/CMS/CutBasedElectronIdentificationRun2
git cms-merge-topic lsoffi:CMSSW_9_4_0_pre3_TnP

# BEST (top vs qcd tagging)
git clone https://github.com/cms-ttbarAC/BESTAnalysis.git -b 94X
# LWTNN (running BEST in c++)
mkdir lwtnn
git clone https://github.com/demarley/lwtnn.git -b CMSSW_8_0_X-compatible lwtnn/lwtnn

## This framework 
#  without the submodules:
git clone https://github.com/cms-ttbarAC/Analysis.git   # you need to manually fetch hepPlotter, asimov, & cheetah

# with the submodules:
git clone --recurse-submodules https://github.com/cms-ttbarAC/Analysis.git

Once everything is checked out, compile!

scram b -j8

To set the environment anytime you open a new session:

source setup.csh   # ALWAYS DO THIS FIRST! (initializes everything)
