STAR Flow, Chirality and Vorticity PWG

[Prithwish Tribedy <ptribedy AT rcf.rhic.bnl.gov>]

Hello Egor,
  Sorry for the delay. Very nice slides. Here are my comments. With 
these included I sign-off.

Preliminary approval :
1. All plots: The axes labels, tics and legends on your plots are too 
small to see.

2. Preliminary plot on resolution: Particularly the rising part for BBC 
-- is this consistent with what other see? I know Kosuke and Kishora 
looked at 54 GeV data. For example can you please check if your results 
compare to what was shown here:
https://drupal.star.bnl.gov/STAR/system/files/polarization_tpc.pdf

3. Preliminary plot on Ξ mass:
Somewhere you have to write it's for Ξ -> Λ + π
You can write: M_{inv} [ Ξ -> Λ + π ] or something like that.
Is this for Ξ or Ξ-bar or sum ? You have mention that.

4. Preliminary plot on EP method:
What is Δφ^{*} is not specified. Is this the x-axis then write 
Δφ^{*}=Ψ_1 - φ^* in the x-axis label.

5. Preliminary plot on Energy dependence:
"STAR Preliminary" is missing.
In the legend you write "Preliminary" but I think you have to say "STAR 
Preliminary" there.


Talk approval:

slide#4:
emitted in --> emitted along

slide#4:
Ψ_1 and it's resolution --> Ψ_1 and its resolution

slide#4:
The figures need reference

slide#4:
Here you have to say for Ξ, in some cases you measure the polarization 
using two methods: "via decay Λ daughter" and "via direct method".

slide#5 (optional comment):
Ξ polarization may provide new input for global polarization and 
vorticity studies
-->
Global polarization Ξ may provide new insights on vorticity studies in 
heavy ion collisions


slide#6:
Did you miss "Event Plane Detector" ? You used EPDs for 27 GeV analysis 
right ?


slide#7:
"Event plane Ψ_1 can be measured spectators signal at high-rapidity 
detectors"
-->
"Event plane Ψ_1 can be measured by detectors at forward rapidity where 
directed flow is large"

slide#7:
To define "Resolution" you write "EPD" but for 54 GeV you use BBCs this 
can create a confusion. Also, East and West are STAR convention. How 
about Ψ_{1,Forward η} and Ψ_{1, Backward η}?

And then somewhere on slide#7 you have to write that you use EPD, BBC, 
ZDC.

Did you use KF-particles ? If yes it would be good to mention it here.


slide#7:
labels and legends on the plots are very difficult to see.

slide#8: Define Δφ^*.

slide#9:
"polarization congruence at difference collision energies"
You see congruence of what with what?
Did you mean Ξ results show congruence with Λ results ?

Best,
Prithwish
