STAR HardProbes PWG

["Ma, Rongrong" <marr AT bnl.gov>]

Hello Wei

I was asked by the STAR management to take a look at your poster. Here are 
some comments for your consideration. 

General
- In the poster title, "S" should be in lower case for "\sqrt{s_NN}"
- You have 7 references, but it is not clear where they are actually referred 
to in the main text. Please indicate that. 

ABSTRACT
- transverse momentum -> transverse momentum (p_T)
- Beam energy dependence of J/ψ RAA is discussed together with model 
comparisons. -> The J/ψ R_AA increases with p_T, but remains almost unchanged 
against beam energy. (You do not discuss any model comparisons in your poster)

MOTIVATION
- Rephrase the first bullet "In relativistic heavy-ion collisions, J/ψ R_AA 
can be affected by various effects, including dissociation, regeneration, and 
cold nuclear matter effects."
- Rephrase the second bullet "Variation of these effects with collision 
energy implies the possibility to disentangle them by measuring energy 
dependence of J/ψ production."
- Rephrase the third bullet "Data collected by the STAR experiment during 
BES-II provide a valuable opportunity to carry out such measurements."

STAR DETECTOR
- Move the section title to the middle
- Make the plot a bit smaller such that it is not so close to the title
- Extend to higher P_T with velocity -> Extend PID to higher p_T

ANALYSIS PROCEDURE
- Replace the first bullet with "J/ψ -> e^+ + e^-, |\eta| < 1"
- Add a bullet to the lower right "Fit UL distribution with three 
components", and then make the current three bullets all as sub-bullets
- J/ψ Shape: simulation accounting for detector effects. ->  J/ψ shape: 
detector simulation.
- remove "unlike-sign distribution" after "mixed-event"
- For all three figures, please make the x-axis and y-axis titles and labels 
a bit bigger

RESULTS AND CONCLUSION
- Title: conclusion -> conclusions
- First bullet
-- measured -> measure
-- \sqrt{s_NN}= 14.6 -> \sqrt{s_NN} = 14.6 
-- and 27 GeV -> and 27 GeV, which extends the previous measurements to lower 
energy and fills the gap between 17.3 and 39 GeV
- Merge bullets 2-4 into a major bullet "Significant suppression of J/𝜓" with 
three sub-bullets: i) R_AA increases with p_T, ii) no significant energy 
dependence, iii) hint of decreasing R_AA with centrality
- Fifth bullet: remove
- In the future , We will measure the -> Outlook: measure
