Hi Ziyang,

   Thanks for preparing this nice proceedings. Please find some comments from me below

L13: by heavy-ions in the very early stages of collision

L13: I think the part from such as to of the EM fields at the beginning of L16 can be removed. 

L22: Remove the sentence starting 'The measurements are '

L29: a large sample

L29: Remove 'of datasets'

L34: Remove 'finally'

L36: Remove mass range for J/Psi

Sec 2: Can you separate out the discussion of the two analyses. It now reads unclear as which refers to which. Discuss the triggers and background subtraction and fitting for J/Psi and then discuss the dimuon analysis

There also needs to be a short discussion on the efficiency correction and major systematic uncertainties

L54: suppression --> modification

L58: Need to mention from where the p+p yields are taken from

L58: centrality bins

L60: Remove 'strongly'

L62: ~ to approximately equal to sign

L63: You need to add a sentence to explain what the slope parameter is related to, probably just the same sentence in Ref. 4

L66: calculation, indicating photon induced production

L71: Its < 0.1 GeV/c in the figure

L72: explain which theoretical calculation

L73: Why Fig.6 is discussed before Fig.5? If so, switch the order of figure

L73: Seems Fig. 6 should come first, then Fig.5 and then Fig.4 from the progression of discussion

L77: Can remove the sentence 'It indicates'. Same physics is discussed in that of Fig.5

L84: confirms  

thanks

Hello Ziyang,

Thank you for implementing my comments.
I have a few additional comments. With these implemented I sign off.

L10: "very-low-pT" -> "very low pT" [ hyphen is not needed here]
L15: "a lack of experimental measurements of the properties …" -> "…a
lack of measurement to study the properties…"
L55: "..is used.It is …" -> "…is used. It is…" [put a gap between]
L56: "Where Ncoll …" -> Where the Ncoll…"
L61: " -t (-t ~ pT^2) " ->  " -t (~ pT^2)" [ is not that OK?]


Cheers
Nihar
