The purpose of this page is to document the supplemental muon DQM developed by the B PAG to monitor low-mass di-muon resonances.

What selection is applied to muons?

  • Global Muons for both Tag muons and Probe muons

Which triggers are monitored?

  • Low pT single muons trigger, HLT_Mu3

How are the fits run?

  • The invariant mass distributions of All and Passing Tag 'n' Probe pairs are fit simultaneously with maximum likelihood
  • The looked-for efficiency is incorporated as a parameter of the fit and the errors are calculated by the fitter
  • example fit:

Where is the code?
