Questions/Answers

Red led Which dataset are you using (2015 and/or 2016)? Which reprocessing or prompt reco?

Green led ANSWER 2016 Rereco

Red led If the definitions of the muon ID and Isolation variables you are using do not correspond to the official working point, could you explain us why?

Green led ANSWER It is official one.

Red led Are the efficiencies taken from central numbers or recomputed individually for the analysis? (reply for ID, Iso, Trigger)

Green led ANSWER Yes all scale factors are taken from central numbers for ID,Iso and Trigger Red led If the efficiencies are recomputed, are there plots showing level of agreement with central results? (reply for ID, Iso, Trigger)

Green led ANSWER

Red led In case of disagreements, are those justified by differences in selection/particularities of the analysis? (reply for ID, Iso, Trigger)

Green led ANSWER

Red led How are the efficiency numbers used? Are they applied as scale factors to MC? In bins of eta/pt? (reply for ID, Iso, Trigger) Green led ANSWER Yes they applied as scale factors depending the eta and pt of muon for ID, Iso and Trigger.

Red led Which are the errors assigned to efficiencies? How do they exactly propagate into the analysis? Are there systematic uncertainties computed and propagated into the analysis that account for differences between Zs and analysis phase space? (reply for ID, Iso, Trigger) recommended Central errors depending on the eta and pt of muon varied up and down and the difference took as uncertainty separately for ID, Iso and Trigger Green led ANSWER

Red led In case no efficiency corrections are applied, is there any systematic error taken into account in the analysis for this? (reply for ID, Iso, Trigger)

Green led ANSWER

Red led How is the momentum scale and resolution taken into account?

Green led ANSWER They are very small in this analysis and not considered. -- MirenaIvova - 2016-07-04
