STAR HardProbes PWG

Hi Nihar,

Thank you for nice comments,I'll take most of them, but there are a few 
details that need explaining

For:
Title:
Measurement of quarkonium production and polarization with the STAR 
experiment
->  I find this was your title "Beam energy and system size dependence 
of heavy flavor production at STAR"
And also it sounds more informative than what you have now.

the presentation include sequention suppression for psi2s and uplison, jpsi 
polarization, energy and system size dependence. I think the title "Beam 
energy and system size dependence of heavy flavor production at STAR"  don't 
include sequention suppression for psi2s and uplison,jpsi polarization.

For:
slide5
What about 200 GeV?
we think no significant pt dependence for 200GeV(STAR Collaboration, Phys. 
Lett. B 797 (2019) 134917)

I think one important observation : R_AA approaches to unity at beam 
energy around p_T 3-4 GeV/c.
I konw at 14.6 and 27GeV(p_T 3-4 GeV/c.) result close to 1, I thinks It's 
hard to say because the larger statistical error(we can see 19.6GeV result(at 
p_T 3-4 GeV/c.) about 0.6 not 1)

For:
Slide11: "Centrality dependence seems be closer to that at SPS than at 
LHC" -> It is not clear from this figure. Please rephrase exactly what 
you want to say

I mean the isobar reslult trend close to NA50(sps) result,So I add the 
"trend", Thanks for reminding.

Slide17:
You need to introduce "ETOF, EPD"

I thinks there is not enough time to discuss these in detail,so I remove it.


best,
Yan
