STAR Flow, Chirality and Vorticity PWG

[Richard Seto <seto AT ucr.edu>]

Vipuli,

Nice comprehensinve proceedings.

Most of the correction are grammar and wording, expect for an important change in the v_3 physics (indicated below)

P1 column 2. "The observed phase transistion...." ->

"Lattice QCD calculations indicate that the phase transition in the low mu_B region is a smooth crossover at Tc of about 150 MeV [give the reference]. In the high mu_B region of the QCD phase diagram, the transition is expected to be first order ending at a critical end point as one progresses to lower mu_B [give a reference]. An expected...."

Maybe you can get away with not referencing the Lattice(low mu_B) and analytical (high mu_B) calculations if reference 2 gives those references. Are you limitted to 6 pages. I will assume that you are.

P2

"the" after "explore" so it says "explore the QCD...."

Even though you are low on space, you need to give a reference for BESII. You can probablty get away with nor referencing BES I, if your reference to BES II references BES I. You showd reference NA61 etc - but you don't have room. Hopefullyreference 2 has those and you can get away with it.

Section 2.

You can shorten the first paragraph to save space, if that helps. Here is a suggestion: 

"RICH is a highly versatile collider, capable of colliding various nuclear species (U, Au, Ru, Zr, Cu, Al, O, He3 and d) and protons, at energies between 7.7 GeV and 200 GeV center of mass, and from 3.0 to 7.7 GeV in fixed-target mode."

Bottom of column 1

"Following a major upgrade, STAR provides full azimulthal coverage over a wide range in rapidity as depicted in Fugure 2. Large...."

secction 3

par 1, line 7, "as [5]" -> "[5]"

P4

For the faraday effect use [11]. For the transported quark effect you should probably reference the arXiv: https://arxiv.org/abs/2304.02831 since it has not been published yet.

4.3

This is a very important major correction to correct the physics message:

"An initial triangular shape in the initial geometry will result in a triangular flow v_3. This triangular shape, at higher energies, is attributed to even-by-event fluctuations in the positions of the participating nucleons, and is uncorrelated to the initial reaction plane PSI_1. At lower energies (sqrt_sNN=3 GeV) a triagular flow correlated to the reaction plane is clearly seen as shown in figure 4, indicating that the triagular shape arises from dynamical effects due to stopping, the passing time of the spectators and the expansion of the fireball. The values of....."
