Hi Subhash and Zhenyu,

Many thanks for your suggestions and comments!

Collectivity at High Baryon Density from STAR BES-II | The STAR experiment star.bnl.gov

The draft has modified accordingly, below is my reply:

s#4: remove v1: and v2:  from the bullet. IMO, the bullets are valid for  
both vn'sBTW, by "constituent interaction" do you mean partonic/hadronic  
interactions?

Yes, I mean v2 is sensitive to the partonic/hadronic interaction, while I am not sure it’s also valid for v1 in my knowledge.

s#19: You mentioned 4.5 GeV is the onset of partonic collectivity, what  
happened to the ratios above 4.5, is it possible to include in the figure?

Yes, I have added the 7.7 GeV ratio. 

Since we don’t have the Preliminary results at 7.7 GeV, these data are taken from BES-I, Phys. Rev. C 88 (2013).

The NCQ scaled v2 and ratios can be found in the attachment.

For s#19 figure, we want to focus on pT integrated v2 and NCQ scaled v2 ratio at 3-4.5 GeV, 

The X-axis extend to 7.7 GeV would make the pT integrated v2 overlapped too much, thus I add 7.7 GeV ratio in the edge.

Kindly let me know if you have further comments.

Thanks,

Li-Ke

Dear Li-Ke,

Very nice and clean slides. I have a few additional questions/suggestions:

s#4: remove v1: and v2:  from the bullet. IMO, the bullets are valid for  
both vn'sBTW, by "constituent interaction" do you mean partonic/hadronic  
interactions?
s#6: "Hadronic dominates" --> can you re-word e.g. dominant hadronic  
interaction or hadronic interaction dominates
s#8: "Hundreds of millions events recorded at Au+Au 3.0 - 4.5 GeV" --> the  
line is redundant, you already have events listed in the table. You can  
probably mention e.g. FXT data provide good precision for collectivity  
measurement
s#13: is not need --> is not necessary
s#14: baryonic Mean FIeld
s#19: You mentioned 4.5 GeV is the onset of partonic collectivity, what  
happened to the ratios above 4.5, is it possible to include in the figure?

I sign off with these addressed.
