STAR Protected

Update 08.29.2018 -- Run 9 pp: R = 0.2 unfolding, weird behavior in the eTtrg = 15 - 20 bin

If you were to look at the 'eTtrg = 15 - 20' GeV bin of the unfolded 'R = 0.2' data, you'd see a weird bump around 'pTreco = 3' GeV/c in both the pi0- and gamma-triggered distributions:

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:

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

Update 08.24.2018 -- Run 9 pp: analysis flow

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

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

Improving Pion pT and M Cuts for Run 15

Update 08.22.2018 -- Run 9 pp: unfolding with a different response, pi0 and gamma triggers (R = 0.2)

Following up from earlier today:

Update 08.22.2018 -- Run 9 pp: purity, zT systematic

Previously, I tried averaging the purity between 2 adjacent bins of zTtrk:

Update 08.22.2018 -- Run 9 pp: unfolding, pi0 and gamma triggers (R = 0.2, eTtrg = 9 - 20)

After examining how the Run 9 gamma-rich purity varies with zTtrk, I attempted to unfold both pi0 and gamma-rich triggers in all 3 bins of eTtrg for R = 0.2.  The response matrix I used to unfold

Update 08.20.2018 -- Run 9 pp: purity, testing zTtrk cuts

Earlier today, I looked at the zTtrk dependence of the Run9 purity:

Update 08.20.2018 -- Run 9 pp: a few checks on the gamma-rich purity

Following up on the previous study of the Run9 gamma-rich purity:

Updated spectra with new version of fastsim

 Dpm spectra for centralities 0-10, 10-40, 40-80 and 0-80 with new binning (to match Guannan's D0) and new version of fast simulator. There is still a difference in pT dependence...
