Hydjet Validation for Dilepton Group Z0 Analysis

1. Previous Study

21XHYDJET production information

* decache location : /pnfs/cmsaf.mit.edu/t2bat/cms/store/user/davidlw/HYDJET_GEN_X2_MB_4.0TeV/HYDJET_GEN_X2_MB_4.0TeV/545444c24aba01a433ce34e4c379212c/

* 100k production by Wei at CMSSW_2_1_X

Jpsi And Muon pt distribution

  • Note : This result includes double counting in the J/psis and muons, which means that some of particles decayed several times as themselves.

2. Quarkonia on 2.76 TeV Hydjet Samples (Quarkonia and Weak bosons off , done by Mihee)

Data samples are located under MIT T2 servers. In the DBS, dataset name is :
  • 2.76 TeV (~ 1M events) : /Hydjet_Quenched_MinBias_2760GeV_MC_3XY_V24_GEN-SIM-RAW/davidlw-Hydjet_Quenched_MinBias_2760GeV_MC_3XY_V24_GEN-SIM-RAW-51550601a6965131c06787129d40c7a9/USER

Jpsi And Muon pt distribution

3. Quarkonia on 2.76 TeV Hydjet Samples (Quarkonia and Weak bosons on)

Data location (94800 events)
  • /castor/cern.ch/user/d/dmoon/cms352/HydjetMinBias_2.76_QWon6
cfg file
  • /afs/cern.ch/user/d/dmoon/public/html/HydjetValidation/Hydjet_MinBias_2.76TeV_QWon6_cfg.py

Jpsi And Muon pt distribution

The conclusion

  • They are not much different, because they are using MSEL = 1, we need to change this parameter.
  • old default setting, including quarkonia setup is here

  • in ppdfault MSEL should be changed from 1 to 0.
       * parameterSets = cms.vstring(
                'ppDefault',
                'pythiaUESettings',
                'pythiaJets',

                'pythiaQuarkoniaSettings')
    
         
  • have a look at here, if you want take this setting
