Trigger Simu Test

I am trying to figure out why the trigger simulator only returns as 'good' a fraction of the events returned as 'good' by the online L2-gamma trigger.  Let me state that a different way...

Updated Charged Pion A_{LL} predictions

Received some new NLO pQCD predictions from Werner incorporating DSS fragmentation functions.  Here's a comparison of these predictions to the old mocked up ones used in the SPIN 2006 preliminary result:




No really dramatic changes here.  The increased asymmetries might mean that g-g scattering is even more important than predicted originally.  Of course, this goes in the wrong direction if we're looking for better agreement with our Pythia.

online QA test

I'm attaching two pdfs showing the online QA plots from run 8330100 for the EEMC trig HT input, DSM layer-0 and BEMC trig BEMC DSM LO input - High Tower. Let me know if they look reasonable??

2008 BEMC Preliminary Timing Curves from L2 Data

Jan Balewski suggested that I try to determine the BEMC timing curves
from L2 data.  Here is my first attempt from the data Oleg Tsai took a few days
ago:

Single-particle results

These plots were generated from 30 files of 2000 events each, for a total of 60000 kaons.  There are 128788 Pixel hits, 181764 Ist hits, and 43606 Ssd hits:

Can we get asymmetry in Re{A11} from GenBod?

The goal of this study: 

Asymmetry in Re{A11}

AuAu@19.6GeV: Data selection

1. Event selection

 

AuAu@19.6GeV: SH moments - why some bins are not shown on plots?

Some bins are not shown on the plot like for example 1st and 4th bin in A10 on left figure below because they are above the scale.
