STAR Flow, Chirality and Vorticity PWG

[ShinIchi Esumi <esumi.shinichi.gn AT u.tsukuba.ac.jp>]

Dear Chunjiang

I sign off your nice poster with a one minor comment. 

For the "size-flow” transmutation in your Result title, I would say “shape - flow” transmutation 

as you mentioned in the Summary and/or it would also tell us about “radial - anisotropic flow correlation”. 

Best regards, ShinIchi

Dear Chunjian,
Very nice poster! Please consider the following comments -- with these included I sign off your poster.

Logo of funding & support:
I think you need to add DOE logo saying "partially supported by" and your institution logo somewhere.

Title:
"flow-mean transverse momentum correlation"
-->
"flow & mean transverse momentum correlation"
or
"correlation between flow & mean transverse momentum"

Motivation:

"Shape-flow transmutation"
-->
"Shape-flow transmutation in deformed nuclear collisions"

It seems the left cartoon is only valid for prolate shape nuclei right ? Oblate nuclei will have opposite shape-flow correlation. So, maybe we should say "prolate-nuclei" somewhere.

Normally the equation you wrote for nuclear density should have a general form that contains β4 which is non-zero for Uranium. If you write this, you should say "leading form of nuclear density".

"A large uncertainty in the well-deformed 238U deformation value"
-->
"A large uncertainty in the β2 parameter of highly deformed 238U"

We had some discussions during the PWG meeting about the right plot of v2{4}. Be prepared
to clarify the connection between this plot and deformation.

Observables:

I think somewhere here you should say something about the dataset and detector you used: "STAR data for Au+Au 200 GeV from year 2011, and U+U 193 GeV from year 2012 and TPC detector".

Change "<(p_T>)" --> "<(p_T)>" where the black arrow is pointed

It is not clear what acceptance is used for the estimation of <pT> in case of
"2-subevent" "3-subevent", can you modify this accordingly ?

Results:
"v2-pT correlation demonstrates size-flow transmutation"
-->
"v2-pT correlation demonstrates shape-flow transmutation"

"TRENTo can reproduce data quantitively"
-->
"TRENTo can reproduce data quantitatively"

"Subevent calculation could decrease non-flow contributions"
-->
"Subevent calculations indicate decrease of non-flow contributions"
or
"Subevent calculations hint decrease of non-flow contributions"

"IP-Glasma Hydro"
-->
"IP-Glasma + Hydro"  or "Hydro with IP-Glasma initial conditions"

Reference to "TRENTO" & "IP-Glasma" models need citations, I suggest you add the following somewhere:

"Theory predictions are based on:
TRENTO: Giuliano Giacalone, Phys.Rev.C 102 (2020) 2, 024901
IP-Glasma: Schenke, Shen, Tribedy, Phys. Rev. C 102 (2020), 044905"

Summary:

"We presented a clear shape – flow transmutation."
-->
"We presented measurements from STAR that demonstrate a clear shape – flow transmutation"

"Subevent methods is consistent with standard methods and also could decrease"
-->
"Subevent results are consistent with that from the standard method and indicate decrease in"

Maybe add a line in the Summary:
"These measurements provide novel ways to constrain nuclear deformation in heavy-ion collisions"

Best,
Prithwish
