HighMassLFV analysis package

Description

This project contains the analysis code used for the Exotics LFV search.

• read flat Ntuples created by HighMassLFV package
• make Background control plots
• make W+jets and QCD background extimation
• make all needed plots

It consists in a collection of several tools, later explained.

N.B: in the future most small tools will be merged in single tools depending on their purposes (i.e. All bkg estimation will form BkgEstimation tool)

Compiling: first compilation

This package needs a recent version of ROOT

• login on lxplus
• setup ATLAS software (type 'setupATLAS')
• go to HighMassLFV_Analysis working directory
• setup ROOT release (type 'lsetup ROOT')
• compile (type 'make')

Running

• go to the working directory and set the environment type 'source config.sh')
• then compile the package (type 'make')

Cascade of tools

• AdjustFakeRate -> arrange tau fake rate inputs in a single file
• makePlots.py -> call RunOnMiniTree to make starting plots
• mergerQCDInputs.py -> merge LepFake and DoubleFake root files
• MakeQCD -> make QCD contribution evaluation
• AddContributions -> add W+jets and Top fit
• MergeContributions -> make Multijet and BkgTot plots
• SysPercentVariations -> make percent variation for each sys uncertainty
• CreateSysBands -> create the systematic bands
• LimitInputs -> create inputs for limits calculation

Top Fits

• TopExtra -> arrange all top plots in a single file per channel as fit inputs
• TopScale -> make top scale ratio w.r.t nominal case to derive sys to be applied to other distribution
