SingleTrackTurnOns

This is a simple setup for checking the single track trigger efficiency in data . One needs to aware that the trigger efficiency is combined HLT and L1 efficiency altogether. Also, the trigger efficiency is defined as

 leading pT distribution (higher threshold/lower threshold)

where the higher threshold cannot have any prescale, and the lowest threshold is calculated w.r.t MB trigger.

STEPS:

  • Checkout at least 75X, and git clone this repo 
     git clone https://github.com/KongTu/SingleTrackTurnOns.git
  • Compile. 
     scram b -j4
  • Go to /SingleTrackTurnOns/turnOnMaker/test, and replace the input file name, double check the track quality cuts and calo matching resolution parameter, before you do: 
     cmsRun HLTandL1singletrack_crab_cfg.py
  • One can use /macros/L1plusHLTSingleTrackTurnOns.C to plot efficiency as function of pT.
