July Exercise the First Measurement for Z0 Analysis

How to get this

  • 2 Skims : Skim0 + Skim1(ZToMuMuSkim?)
  • cvs co UserCode?/CmsHi/Z0Ana
  • mv UserCode?/CmsHi/Z0Ana .
  • scramv1 b
  • cd Z0Ana?/ZToMuMu/test
    • Muon skim : muonSkimPatRecoTemplate_cfg.py
    • ZtoMuMu? skim : ZToMuMuSkim?_cfg.py
    • ZtoMuMu? Plot : ZToMuMuPlots?_cfg.py
    • Mass macro : Z0MassFit?.C

1. 2nd Enriched Sample Analysis (2010/07/12)

  • ZtoMuMu? Skim location : /castor/cern.ch/user/k/kumarv/JulyExercise/

1. Dimuon Mass spectrum

  • Global + Global Dimuon Mass spectrum
  • Global + StandAlone? Dimuon Mass spectrum
  • StandAlone? + StandAlone? Dimuon Mass spectrum

2. 1st ZToMuMu? Skimmed Data (2010/07/06)

  • ZtoMuMu? Skim location : /castor/cern.ch/user/d/dmoon/JulyExercise/cms370/DileptonMuSkimZToMuMu2
  • ZtoMuMu? Plot root location : /castor/cern.ch/user/d/dmoon/JulyExercise/cms370/DileptonPlots

1. Some plots of First Measurement

Dimuon Mass spectrum

  • Global + Global Dimuon Mass spectrum
  • Global + STA Dimuon Mass spectrum
  • STA + STA Dimuon Mass spectrum

Single Muons

  • Global Muons pt
  • STA Muons pt

Conclusion

  • According to the Dimuon Mass spectrum, we found Mass peak of Z0 at STA+STA
  • It seems to have a problem, because the STA is the subset of GLB(global muons)
  • It turns out that the sample was not correctly made at vertex matching.
