Which plots are in the Top Muon HLT DQM?

14 Efficiency related plots:
     D0, Z0, Charge, eta, phi, pt, pt_max
     7 distributions * 2 histos/distrib = 14 plots
6   Fake related plots: pt, eta, phi (ONLY produced for HLT Triggers)
1 Charge Flip
2 isolation
4 Beamspot track parameters: D0, Z0 eff from beamspot
2 Phi Vs Eta
3 Resolution: Pt, eta phi

Examples of plots

• A talk demonstrating some of the plots is available on indico: http://indico.cern.ch/conferenceDisplay.py?confId=68436
• A pdf with just the plots and no explaination is available here: https://twiki.cern.ch/twiki/pub/CMSPublic/SWGuideMuonHLTTopPAGDQM/ttbar_3_1_0_pre9.pdf
• The top DQM was run on a sample of events used in the October Exercise. The results are documented CMS.OfflineHLTDQMTopOctX

What selections are used on the muons that go into these plots?

The selections are available in the CMSSW CVS. There are two configuration: COSMICS and COLLISIONS.

Specifically, the selection for CRAFT09 cosmic data is:

collectionName = cms.untracked.string ("TopCosmicConfig3"),
trackCollection = cms.untracked.string ("outerTrack"),
requiredTriggers = cms.untracked.vstring(""),
d0cut = cms.untracked.double(1000.0), # any where
z0cut = cms.untracked.double(1000.0), # any where
recoCuts = cms.untracked.string ("abs(eta) < 2.0"),
hltCuts  = cms.untracked.string ("abs(eta) < 2.0")

In other words, we select stand-alone muons with |eta| < 2.0, and any d0 or z0, and match them to hlt muons with |eta| < 2.0.

[b]Currrently, we also require >= 2 jets.[/b]

The purpose of this selection is to put events in the histogram to make sure that we can see events going through the whole workflow. These events won't be top-like.

Where is the source code?

The relevant files are:

DQMOffline/Trigger/src/TopTrigAnalyzer.cc

Here are instructions for running the code

ssh lxplus5
scram project -s CMSSW CMSSW_3_6_0_pre2
cd CMSSW_3_6_0_pre2/src
