  • 1) SUS-13-007: covers the single lepton + btag using the Lepton Spectrum (LS) and Delta Phi (DP) methods. Lepton studies are documented in AN-2013-035. Analysis notes: AN-12-390 and AN-12-416. Pre-approval date: Fri, Feb 1, 2013. Targeting Moriond.
 
  • 2) AOD rereco is used for periods A, B, and part C; prompt reco is used for part C and D.

  • 3) Efficiencies of leptonic and hadronic legs are shown to be not strongly correlated, thus they are measured separately. The lepton legs are mesured via Z T&P in events that are acquired by the analysis triggers (therefore with correctly biased kinematics).

Trigger efficiencies: scale factor is to be applied on Monte Carlo. Individual triggers are listed with scale factors and systematic errors. "Overall" is a value that is compatible with the result of every trigger in the table. In case of the muons, additionally, a correction is to be applied on the scale factor different for barrel and endcap to account for eta dependence.
