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

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.
