• Discussion with Catherine (13:40~14:00)
  • At first, we need to try test with simple pythia minbias config file
  • Sample file link : https://cmsweb.cern.ch/dbs_discovery/getAppConfigs?dbsInst=cms_dbs_prod_global&appPath=*&procPath=/RelValProdMinBias/CMSSW_3_5_4-MC_3XY_V24-v1/GEN-SIM-RAW&ajax=0&userMode=user
  • Modifyed some part
    • comEnergy = cms.double(4000.0) (7TeV->4TeV)
    • EML option (default): process.g4SimHits.Physics.type = cms.string('SimG4Core/Physics/QGSP_BERT_EML')
    • HP option : process.g4SimHits.Physics.type = cms.string('SimG4Core/Physics/QGSP_BERT_HP')
• Result
  • PHTHIA - 4TeV, normalized by no. of events
    • EML : (CSC/DT/RPC) - (0.07/0.00/0.00)
    • HP : (CSC/DT/RPC) - (1.15/0.01/0.00)
  • HIJET - 2.76TeV from Dong Ho, normalized by no. of events
    • EML : (CSC/DT/RPC) - (56.19/3.84/0.50)
    • HP : (CSC/DT/RPC) - (59.00/3.90/0.48)
• Test and modifying
  • Proposal by Catherine : remove UE(Underlying Event) part

         parameterSets = cms.vstring(
             #'pythiaUESettings',
             'ppDefault', 'pythiaPromptPhotons', 'pythiaJets', 'pythiaZjets',
             'pythiaBottomoniumNRQCD', 'pythiaCharmoniumNRQCD', 'pythiaQuarkoniaSettings', 'pythiaWeakBosons')

• • Batch job with no different seeding -> no different sample -> Adding seed part, _ N _ : No. of each file

process.RandomNumberGeneratorService.generator.initialSeed = _N_
process.RandomNumberGeneratorService.VtxSmeared.initialSeed = _N_
process.RandomNumberGeneratorService.g4SimHits.initialSeed = _N_
process.RandomNumberGeneratorService.mix.initialSeed = _N_
process.RandomNumberGeneratorService.mixData.initialSeed = _N_
process.RandomNumberGeneratorService.simSiStripDigis.initialSeed = _N_
process.RandomNumberGeneratorService.simEcalUnsuppressedDigis.initialSeed = _N_
process.RandomNumberGeneratorService.simHcalUnsuppressedDigis.initialSeed = _N_
process.RandomNumberGeneratorService.simMuonDTDigis.initialSeed = _N_
process.RandomNumberGeneratorService.simMuonCSCDigis.initialSeed = _N_
process.RandomNumberGeneratorService.simMuonRPCDigis.initialSeed = _N_
process.RandomNumberGeneratorService.simCastorDigis.initialSeed = _N_

B2Jpsi2mumu Generator study (on going)

Technical tips (unsorted)

batch job :

bsub -R "pool>10000" -q cmscaf1nd -J B2JpsiGen < mjob_jpsi.csh

bqueues -u hckim

bjobs -w
