STAR Correlations and Fluctuations PWG

[Zachary Sweger <zwsweger AT ucdavis.edu>]

Dear Toshihiro,

Thank you very much for the comments. I've implemented all of them, except I'd like to refrain from explicitly listing the energies, 3.2, 3.5, 3.9, and 4.5, in part because there are some indications that even with the acceptance gap, a result at 5.2 GeV may have a similar significance to the 7.7 GeV collider data point. It's not certain, but I'd like to not close the book on that prematurely. Also we may eventually be able to measure the higher moments away from mid-rapidity at the high FXT energies, as a way to study the behavior at different chemical potentials. Let me know if this edit is okay.

The updated abstract is available here: https://drupal.star.bnl.gov/STAR/system/files/QuarkMatter_2023_PosterAbstract_v2.pdf

Thank you!

Dear Zach,

Please find below for my comments on your nice poster abstract.

Title: Status of the Analyses for the Proton Higher-Order Fluctuations in the 
STAR...

L2: Higher-order fluctuations of the net-proton number distributions in 
heavy-ion collisions are expected to be sensitive to a QCD critical point.

L4: "These fluctuations are ... collision energy."
Rephrase as follow:
"These fluctuations can be obtained by measuring various order of cumulants, 
C_n, of the net-proton multiplicity distributions."

L5-L9: "Proton kurtosis results from... a return to the expected baseline 
behaviour"
This can be rephrased as follow:
"The collision energy dependence of net-proton C4/C2 from Beam Energy Scan I 
hints a possible enhancement  from 19.6 GeV to 7.7 GeV across the baseline,
while the proton C4/C2  value at 3 GeV from the Fixed-Target program (FXT) 
returns to the baseline. These results indicate the importance of filling the 
gap between 3.0 GeV and 7.7 GeV"

L9:-L11  "The remaining .... complicates these analyses."
This can be rephrased as follow:
"The analyses of the remaining FXT data sets for 3.2, 3.5, 3.9. and 4.5 GeV 
are ongoing to fill the gap and to see whether any critical behaviour is 
observed, although limited acceptance...these analyses. "

L12: Remove "Data from ... underway"

Best regards,
Toshihiro
