Run 9 200GeV Service Gap Investigation: Second Look

This is my second look at the effect that the service gap has on jet reconstruction.

Open heavy flavor production

Upsilon production in p+p, d+Au and Au+Au collisiobs

AgML Release Milestone 1

Abstract:  We are preparing to integrate AgML into the STAR software stack.  AgML is the new geometry description language.  Our first milestone has been reached:  we are able to validate the translation of the STAR geometry to AgML for the production geometries from y2009 to present.

Minimum Bias data/simulation EMC cluster invariant mass

     With 70MeV threshold, I use run08 pp minimum bias data (run list in attachment 1) and pp MB sample for run08 (EEMC uncorrected geometry) to

Run 6 variable fit parameters as functions of PT

 Again, same plots as from run 9 but for run 6.

 

Run 6 PT bin fits

 These are the same plots as for run 9, but for run 6. The pion location is clearly around the accepted value, demonstrating the 5% difference in run 9.

TPC Hit Errors changes

For RT Ticket 2103, we would like to understand the changes in TPC hit errors which were introduced in January 2010 for the Run 9 pp500 data.
