Hello All,

I did heavy flavor QA for the HP-PWG. Here is a link to the presentation https://drupal.star.bnl.gov/STAR/system/files/FastOffline%20QA%20For%20Run%2025%20Au%2BAu%20200GeV%20%281%29.pdf

There seems to be a problem with the BEMC in the production. A patch of towers (approx from 200 to 420) give zero ADC in the online but do not in the production. This results in extremely high energy (32.768 GeV) in the picodst files produced.

The one over beta seems to be shifted down below 1.

The nSigma plots seem to be deviated compared to other QA done in the past.

There also seems to be a problem with the pion nSigma where it gives large number of 0 nSigma in the TOF. 

I was going to present those results but due to the cancellation of the meeting, i thought i would give a update so maybe some of these problems could be corrected in the upcoming Fast Offline production.

Best Regards,

Yousif
