• EVO Bridge ID: 1454091
  Title: W-phone, Community: STAR, no password

Agenda

1. W production priority: Bedanga
2. Code readiness : Jerome
3. Data production readines
   • 1/7 of data produced in dev, muDst at: /star/data05/scratch/balewski/2009-muDst-beamLine3/, BFC="pp2009c ITTF VFPPVnoCTB BEmcChkStat beamLine Corr4 OSpaceZ2 OGridLeak3D -dstout -evout", ready for evaluation
   • PPV QA : Rosi
   • beam line : Rosi
   • TPC calib, Joe, Gene
     • SC &GL - going after pileup?
4. Embedding readiness
   • pilot W-embedding request of single high energy electrons(details: http://drupal.star.bnl.gov/STAR/node/16000#pilotEle) to test

     Code Block

     * test how beam line offset used by GSTAR is changed from fill to fill, * test how multiple use of the same ZB events is handled (different M-C seed, different output file name) * test the ZB event time stamp, event ID, run # is preserved * test proper gains for BTOW & ETOW are used * test reco electron energy agrees w/ thrown energy * test chi2/dof for tracks is reasonable * test dedx is reasonable * test raw ADC for all BTOW & ETOW towers are stored in muDst * test correlation between .geant and muDst events * test timing , disk space

   • ETOW gain data/mc - Justin follow up
5. W x-section: Ross
6. AOB

December 1

1. Code readiness
   On November 23 "we created stable SL09f library with all codes from current DEV up-to-date to proceed with calibrations production"
   Shall we use this library as basic platform for:
   • new production of W-daq files
   • generation of M-C events for W-embedding
   • W-embedding itself
2. Embedding readiness
   • weights for ZB events - Jan's blog
   • official description of the W-embedding process in drupal
   • how will it all work together? Pibero
   • BTOW SF & LOW_EM in simulator: Matt.
     Recent plot from Mike 50 GeV ET gamma . Magenta dots show the most likely GSTAR output, black line shows current value of the SF(eta) used in the barrel simulator. If simultor is used 'as is' the reco ET will be off by up to 5%. (plot taken from Mike's blog)
   • pre-embedding comparison of BTOW, ETOW response - Justin blog
3. Data production readines
   • TPC calib, Joe, Gene
     • SC &GL - Done!? comparison of residua, The goal was 300um.
       SC = 3.1e-7*zdcx+5.0e-13*zdcx*zdcx
       GL = 6.69
       Uploaded to DB by Gene
     • dedx - prospects based on BFC production
     • progress on chi2/dof discrepancy for data vs. M-C
   • when STAR libary will be tagged?
4. BTOW 2x2 vs. 3x3 cluster energy - Ilya
5. vernier scan, W x-section: Ross
6. reco Z events invariant mass and charge sign discrimination- Ross
7. AOB
