STAR HardProbes PWG

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

Hello Yan

In the interest of time, here are my comments for your consideration. 

s1
- 200GeV -> 200 GeV

s3
- reverse the order of the first two bullets
- are ideal probes -> is considered a unique probe
- Color screening -> Dissociation (there are also dynamic processes that can 
dissociate J/psi)
- Also add "Feed-down contribution" here

s5
- Here is a high-resolution version of the figure: 
https://www.star.bnl.gov/protected/heavy/aschmah/STAR_3D/STAR_V19_MTD_EPD.jpg

s8
- The R_AA -> R_AA
- isobaric collision -> isobaric collisions
- Highest J/𝜓 precision measurement at RHIC to date -> High-precision J/𝜓 
measurement at RHIC

s9
- due to color screening effect -> due to dissociation 

s10
- Title: trigger -> events

s11
- Title: HT trigger -> BEMC-triggered events

s13
- move "4" and "GeV/c" to the same line
- remove "Most precise 𝑣2measurement to date at RHIC"
- small regeneration -> little regeneration 

s14
- remove "at low p_T range"
- Indicate that the color screening effect is dominant in isobaric collisions 
-> Indicate strong dissociation effect in central isobaric collisions

Best
Rongrong
