DIS 2009 Proceedings - Draft 1.0

J/pis in Cu+Cu 200 GeV - the high pT contribution to dN/dy

Problem: only limited pT range is accessible in Cu+Cu min-bias data (up to 5Gev/c).

Gain studies day 72

I have been trying to optimize the range to fit the gains for the ZDC SMD slats.  I have done two ranges of gain fits and then have set the all parameters for the fit to 1 as well.  The p

ZDC SMD Stability Study II

  A continuation of the ZDC SMD study.  The gains from the response of the SMD slat are obtained from a linear fit of the natural log of the number of hits versus ADC for ADC&nb

GEANT Tune Study

One possible cause of the observed discrepancy between data and simulation in the BEMC is the insufficiency of the nominal tracking parameters in GEANT.

ZDC SMD Stability Study

   I have taken 2 fills, 10364 (March 13, 2009) and 10375 (March 16, 2009), and plotted the stability of the ADC pedestals and gains for all of the SMD slats as a function of time du
