Update 08.28.2018 -- Run 9 pp: raw vs. corrected data (bin-by-bin test)

Yesterday I tried correcting the R = 0.2 (9 - 11 GeV) data with a bin-by-bin procedure:

Update 08.28.2018 -- Run 9 pp: raw vs. corrected data (unfolding, R = 0.2)

The results of the recent unfolding of the R = 0.2 data can be found in these links:

upcoming JAVA licensing changes for 2019

Regarding the upcoming Oracle licensing fee changes (January 2019), it seems to me that STAR need not be affected much, if at all, for the near future.

Update 08.27.2018 -- Run 9 pp: bin-by-bin test

In a recent internal meeting it was suggested that since the corrections in the unfolding process were so small, it might be prudent to switch to a bin-by-bin correction since the process is far more

Flow de-correlation measurement with EPD

In this study, I measured the second order flow de-correlation with the data from AuAu@27GeV and Isobars@200GeV.

Update 08.24.2018 -- Run 9 pp: analysis flow

Just for reference, below is an overview of the neutral-triggered jet analysis flow.

  1. Tag pp events with either pi0 or gamma-rich triggers.

Update 08.24.2018 -- Run 9 pp: measured vs. unfolded data, pi0 and gamma-rich triggers (R = 0.2)

To get an idea of how big the corrections are due to the unfolding procedure and if any odd features appear in the unfolding procedure, I've plotted the raw data and unfolded distributions on top of e
