TagAndProbe Studies for 2012 Z+Jet (Electron) Analysis

Contents:

A quick setup for users

• I used CMSSW_539 for 2012 scale-factors and here is the configuration file from my working package: https://github.com/lovedeepkaursaini/TnP/blob/master/PhysicsTools/TagAndProbe/test/TnPNtuplesMC.py

• You already have trees from my tree-maker file, so following steps would help to analyse those trees.
• To make MC-templates use this file:

https://github.com/lovedeepkaursaini/TnP/blob/master/PhysicsTools/TagAndProbe/test/MCtemp/Templates/tempMedium.C

• this would give you a root file say "Medium.root" which would save MC-templates taken from your TnP-tree for DYJets MC say. You can give this tree as input here:

https://github.com/lovedeepkaursaini/TnP/blob/master/PhysicsTools/TagAndProbe/test/MCtemp/Templates/tempMedium.h

• Then I copy this "Medium.root" file as "ZeeGenLevel.root" in my main directory i.e. https://github.com/lovedeepkaursaini/TnP/tree/master/PhysicsTools/TagAndProbe/test/MCtemp

• For analysing data trees: https://github.com/lovedeepkaursaini/TnP/blob/master/PhysicsTools/TagAndProbe/test/MCtemp/MediumtnpEffiPtEtaBins_cfi.py

• For MC-tree analysis use: https://github.com/lovedeepkaursaini/TnP/blob/master/PhysicsTools/TagAndProbe/test/MCtemp/MCMediumtnpEffiPtEtaBins_cfi.py

• Here is a python file which would help to configure TnP analyser: https://github.com/lovedeepkaursaini/TnP/blob/master/PhysicsTools/TagAndProbe/python/FitConf/MediumtnpEffiStudies_cfi.py

• Here are given various PDFs for background and signal modeling: https://github.com/lovedeepkaursaini/TnP/blob/master/PhysicsTools/TagAndProbe/python/FitConf/tnpFitModels_cfi.py

• There are several files for various selections, you can pick anyone, they all follow similar procedure. Above mentioned ones are for Medium-WP.

Official package:

• ElectronTagAndProbe

For Z+Jets analysis:

• check out this for EGammaCutBasedID-2012:

cmsrel CMSSW_4_4_4
cd CMSSW_4_4_4/src
cvs co -d PhysicsTools UserCode/Lovedeep/TnP/TnP444/PhysicsTools/
cvs co -d CommonTools UserCode/Lovedeep/TnP/TnP444/CommonTools
cvs co -d EGamma UserCode/Lovedeep/TnP/TnP444/EGamma
scramv1 b -j 9
cd PhysicsTools/TagAndProbe/test

• To make ntuples:

cmsRun DataTree.py (for data)
cmsRun setTightTag.py (for mc)

• To analyse ntuples:

cmsRun mcanalyze.py

Electron-ID:
