README

Scripts and libraries I developed for the Z' background and isolation studies performed during my master's thesis project. Note: they are made to be run in the CERN LXPLUS cluster and require ROOT. Plots or datasets are not shared, but the provided code skeleton could easily be readapted to other projects.

Folders

Please find the last version of the scripts in "RUN2_2016" folder.

• Isolation_Studies

  Study of the muon isolation variables.

• Emu_InvariantMass

  Study and plotting of the invariant e-mu mass spectrum.

• Libraries

  Libraries needed to run the ROOT macros.

• ScaleFactors

  Calculation and plotting of the e-mu scale factors

Scripts

• Emu_InvariantMass/emu_invMass.cpp

  Draws the ratio "data / total MC", and the invariant e-mu mass spectrum from stacked MC processes and data

• ScaleFactors/ScaleFactors_triggerOn.cpp

  Draws: scale factors from ttbar and WW, e-mu and mu-mu ttbar reconstructed events, and the fractions from the different mc processes that contribute to SF calculation Calculates SF from ttbar only and then from the weighted contribution of every mc background process

• ScaleFactors/texoutput.cpp

  Produces a .tex output file containing a table with all the output values collected from the scalefactors script

• [.]/evaluate_lumi.sh

  Computes the mc luminosities taken from values contained in input_lumi.py, and saves the result in lumi_mc_file.dat

Notes on how to run this code

Just execute the root macros

root -l macro.cxx
