Quarikonia Study

HI Dimuon HLT study

1. R. Vogt Sample HLT at CMSSW_2_2_9

1) Upsilon 100k events sample are generated

* muons from upsilons

2) L3/L2 upsilon trigger efficiency (vs eta & pT)

* analysis concept

- investigated how many MC upsilons are triggered events,

- trigger condition : the number of muons at one event should be more than 2. And both muons are |eta| < 0.8 or at least one muon are there.

- used analyzer is here L1L2L3HIAnalyzer.cc

2. pythia gun flat sample study

- Generated samples, using pythia-gun for Jpsi and Upsilon

1) J/psis

• Jpsi eta & pt

• Muons eta & pt from Jpsi

• Jpsi eta & pt with some kinematical cuts on muons distribution

• Muons eta & pt from Jpsi with some kinematical cuts

• Jpsi eta & pt with some kinematical cuts (including momentum cuts)

• Muons eta & pt from Jpsi with some kinematical cuts (including momentum cuts)

2) Upsilons

• Upsilon eta & pt

• Muons eta & pt from Upsilon

• Upsilon eta & pt with some kinematical cuts on muons distribution

• Muons eta & pt from Upsilon with some kinematical cuts

• Upsilon eta & pt with some kinematical cuts (including momentum cuts)

• Muons eta & pt from Upsilon with some kinematical cuts (including momentum cuts)
