Recent simulation studies in the EEMC and BEMC

Summary of recent simulation tests in the EEMC and BEMC

List of small, almost trivial, problems with the Monte Carlo

1. Density of polystyrene is 1.032 g/cm^3.  PDB quotes 1.06.

    ===> bicron has density of 1.032 g/cm^3... so that's where it comes from.

Comparison of muon energy deposit in 1st layers of EEMC and BEMC in gstar

Abstract:  Muons are thrown with energy of 100 GeV at eta = 0.025 and eta = 1.85.  Energy-loss distributions in the first layer of plastic and the first layer of lead are compared betwe

  Agenda:

    1)    NPE and e-h Results, publications - Huan, Bedanga, ...
    2)    The next STAR Decadal Plan -  Nu

    3)    AOB

* --====================================================================--*

               Brief Summary:

  0) Attendency: Olga, Jerome, Jamie, Flemming, Helen, Xin, Nu, Bedanga

  1) NPE issues: (i) The management feels there more issues to be addressed by the task force. Based on the discussion and Huan's report at the last

      Analysis Meeting, the management will send a note to the task force. A list of specific checks will be included in the note.   (ii) WIll send a message to

      Editor at PRL regarding STAR paper "Charmed hadron production at low transverse momentum in Au+Au collisions at RHIC" submitted on May

      4th, 2008, 0805.0364. Inform the Editor that we are doing internal cross-checks and the process may take sometime to complete.

  2) S&T review issues: (i) Timely funding and scheduling for R&D at RHIC. RHIC performance for polarized pp collisions, we will request 30 cryo-weeks for

      future runs; (ii) TPC: operation team including software issue. Jim should be part of the solution; (iii) FTPC team: A student from India group (VECC),

      with the help of Terry, J. Syboth and P. Syboth; (iv) Future upgrade scheduling and integrations.

  3) QM09 Proceedigns: potential issues with the eta/s analysis (BulkCorr) and Jet reconstruction (JetCorr).

 

  Notes:

   1) STAR TPC Review (key= star2009),  June 4,5, BNL. Ron Settler (chair). Review report.

Correlating ZDC A_N with Central Detectors

Abstract

 

We want to see if the large A_N we observe in the ZDC at 500 GeV has any correlation with how "busy" the central event is.

Data / MC comparisons for isolation cut, take 2

Abstract:  We apply an energy-dependent correction to the MC energy deposit in the Monte Carlo, in order to "fix" the sampling fraction problem.  Data / MC comparisons are made.

EEMC Simulation Studies - Progress

Data / MC comparisons for isolation cut

Abstract: An isolation cut for the endcap is formed by taking the ratio of the transverse energy recorded by a single tower, correcting it for expected shower leakage, and dividing it by the sum of the energy of towers w/in R<0.3 of the candidate photon.  Data and MC are compared.
