The bullet color coding is the following:

--> PENDING
--> IN PROGRESS
--> DONE

Things that are not clear yet are highlighted in RED.

Introduction

Aim of this study is to investigate the effect of ME0 segments and GE21 in the EMTF

Environment setup

Temporary release (outdate)

Rely on IBs until CMSSW 910 pre3 is out!

Samples

MinBias

So far we collected around 33M minbias events. Target is 40M

Todo:

• GEMCode package:
  • add a function in SimHitMatcher to match ME0 hits to simtrack: done (see SimHitMatcher)
  • a function in GEMDigiMatcher to match ME0 digi to simtrack: done (ME0DigiMatcher)
  • then a matcher called ME0SegmentMatcher to match ME0 segments to simtrack. (todo, call this class ME0RecHitMatcher, similar to CSC and GEM)
  • beyond these, one function to associate ME0 Segment to L1Mu is needed.
• GEMCode package:
  • create a matcher called EMTFMatcher to match EMTF track to simtrack. (replace CSCTFMatcher)
• muon rate analyzer: match EMTF track to ME0 segments

Results

To be included in the Muon Upgrade TDR

Figure	Abbreviated Caption
	Efficiency to match a simtrack in 2.15<eta<2.4 to a L1Mu with BX0 that has an ME21 stub, a GE21 pad, that passes the 98% efficiency GE21-ME21 bending angle cut, and that has an ME0 stub matched within dR<0.4. Efficiency was calculated at PU0 using 200,000 double muon events as input.
	Comparison of the trigger rate of the Stage-2 L1Mu trigger versus muon candidate eta (for 10 GeV pT threshold) at PU200 for various selections. All curves require in-time L1Mu (BX0) with quality >=12 (Run-2 single muon trigger) in 2.15<eta<2.4. Red: no extra requirement on having certain stubs. Green: red + ME21 stub + GE21 pad + pass 98% GE21-ME21 efficient bending angle cut. Blue: green + has ME0 stub matched to L1Mu within dR<0.4. No additional cut on the ME0 local bending angle. Rate was calculated at PU200 using ~170,000 neutrino gun events and 40M minbias events as input
