T3MuCombine

Installing combine code for T3Mu analysis

 git clone git@github.com:t3mucommontools/T3MuCombine.git

The script setupCombine.pl will clone and compile HiggsAnalysisTools and CombineHarvester. Run ./setupCombine.pl for an instruction

Please find information on latest releases here: https://cms-analysis.github.io/HiggsAnalysis-CombinedLimit/

./setupCombine.pl --help

There is just one option to it --Combine, do:

./setupCombine --Combine MyWorkDir

This will produce text file that you need to source to setup everything (just pay attention to the instruction on your screen)

The following settings will be used by default:

SCRAM_ARCH=slc7_amd64_gcc700
CMSSW_11_3_4

Creating Datacards for T3Mu analysis

After compilation:

cd /MyWorkDir/CMSSW_11_3_4/src/CombineHarvester/

And choose your working area; The place for combining all categories is /MyWorkDir/CMSSW_11_3_4/src/CombineHarvester/T3MCombineAll

For UF people: the working area is T3MLimit

./makeTheCard.py --help for an instruction 

(or ./run.py with default root file)

Running limits with toys and hybrid-bayesian

1. Run text2workspace.py with --X-assign-flatParam-prior flag

text2workspace.py mydatacard.txt -o myworkspace.root --X-assign-flatParam-prior

2. [Recommended] Define reasonable ranges for all ranges in your datacard. Suggestion: use a script like python/generate_ranges_sh.py to define a list of parameter ranges (e.g. $RUN2_PARS).

3. Run the limit. Note: the option MINIMIZER_freezeDisassociatedParams is required if you have discrete parameters in your datacards.

combineTool.py -d myworkspace.root -M HybridNew --setParameterRanges $RUN2_PARS --rMin=-5 --rMax 10 --X-rtd MINIMIZER_freezeDisassociatedParams --cminDefaultMinimizerStrategy 0 --cl 0.90 -m 1.777 --generateNuisances=1 --generateExternalMeasurements=0 --fitNuisances=1 --testStat LHC

Produce toys using condor/CRAB
