Rho reconstruction simulation study with FMS+FHC

    I studied the rho+ reconstruction with 10M pythia+GSTAR simulation events.

Unable to find agreement with prior values (again)

 The cross section for the BHT3 trigger is likely to change over time, both from beam-related backgrounds we can't identify and from changes in the gains of the individual towers which we can'

Trying to finalize the BHT3 xs

 I've written about the somewhat double-gaussian approach to fitting the BHT3 vernier scans already, so this is just a brief addendum:

Hi,

Event by event comparison between Energy distributions and fitted distributions (2 photon events). These are events that 

Comparison of high pT Gamma Candidates in filtered MC vs. 2006 data

Information

MC is generated using a gamma filter, modified from one by Mike B.  I use the following cuts:

Table of BHT3 luminosities

 I've attached a table of the BHT3 luminosities in the L2W dataset.

2010.01.07 EEMC response to single photons with y2006h vs y2009a geometries

Monte-Carlo setup

  • Throwing one photon per event
  • Full STAR y2006h/y2009a configurations
  • Throw particles flat in eta (1.08, 2.0), phi (0, 2pi), and en

HOWTO: Print the Pythia event record, and (more importantly) decipher it.

This blog entry will be a work in progress for a while.  
 
I have setup pythia in starsim and generated an event.
