  • We use SingleMu and DoubleMu PDs Primary Datasets (PD), PromptReco (and ReReco when it becomes available)
  • JSONs are constantly updated in this directory as we certify more and more data:

Note: before submitting you need to change the input/output directory parameters and the global tag in the batchJob.pl script:

...

Code Block
cd $CMSSW_RELEASE_BASE/src
cvs co -r V00-09-11 SUSYBSMAnalysis/Zprime2muAnalysis
SUSYBSMAnalysis/Zprime2muAnalysis/setup.csh # This last command checks
                                            # out other packages and
                                            # executes scramv1 b to
                                            # compile everything.
cvs co /UserCode/ASvyatkovskiy/AcceptanceAdam
#rearrange stuff a little bit
cp /UserCode/ASvyatkovskiy/AcceptanceAdam/* .

one One needs to configure pT and eta cuts foe for each muon from with the in  the script. This is done very easily in two places:

...

Code Block
loose_cut = 'isGlobalMuon && isTrackerMuon && ' \
            'pt > 10. && ' \
            'abs(eta) < 2.4 && ' \
            'abs(dB) < 0.2 && ' \
            '(isolationR03.sumPt + isolationR03.hadEt) / pt < 0.15 && ' \
            'globalTrack.hitPattern.numberOfValidTrackerHits > 10 && ' \
            'globalTrack.hitPattern.numberOfValidPixelHits > 0 && ' \
            'globalTrack.hitPattern.numberOfValidMuonHits > 0 && ' \
            'numberOfMatches > 1 && ' \
            'globalTrack.normalizedChi2 < 10 ' # + trigger_match

To configure the trigger path for trigger match:

...

Note: plot 40 was produced with LKTC method, code for which is currently not public and not possible to be retrieved from the authors. Currently (2011 data) the result is consistent with that obtained with Tag-And-Probe.

Step 6: Background estimation

There are various methods employed to estimate the QCD background in a data-driven way (QCD is currently the only background estimated not from MC). The most important are the template fit method and the weight map method: carefully read chapter6 of the CMS-AN-11-013 for more details on the methods.
