Hi Neil,

thanks for the clarification. It sounds good to me. 

Cheers.

Hi everyone, thank you for your comments on v2. I have implemented most of the suggestions. Please find some inline responses below.

L8: Why is it qualitatively different from that of inclusive hadrons? The CMS D0 measurement is also showing a redistribution to higher radial distances, isnt?

A: The CMS D0 measurement indicates a redistribution to higher radial distribution. While I couldn't find a direct comparison to inclusive hadrons at the same energy, at 2.76 TeV, Figure 4 2nd plot here shows the behavior to be different for inclusive hadrons.

L5-6: ...  is suppressed for heavy quarks, such as charm and bottom, at low transverse momenta (pT) - this is not clear to me. Do you mean the dead-cone effect ? Please note that for HF at low pT (here it might be also ambiguous what one calls the low pT) the collisional energy loss is expected to be (even more) important. There is also expected mass ordering in the case of the collisional energy loss, but one shouldn't mix the two effects.

A: Here, I am talking about the dead cone effect. I don't mention collisional energy loss processes, because what constitutes as low enough pT for collisional effects to be significant is a little unclear at 200 GeV. Once we have the measurement, a comparison to the existing models like CCNU might be more revealing.

I have uploaded the latest version here: https://drupal.star.bnl.gov/STAR/system/files/APS2022_DiptanilRoy_v3.pdf

Please let me know if you have any further comments/questions.

Hi Diptanil,

Thanks a lot for the nice abstract. I have some minor comments/suggestions on v2 for your consideration. 

 L1: Partons i.e. quarks and gluons --> Partons, i.e.  quarks and gluons, 

 L6: A measurement --> The measurement 

 L11: "making STAR ideal for similar measurements" reads a bit strange to me, how about "allowing us to investigate deeper on it" (or something like this? "similar measurements" sounds not that impressive).

 L!2: and D0 meson radial profile --> and the D0 meson radial profile 

 

Cheers,

Yi

Hi everyone, please find my contribution for DNP 2022 in the link above. The abstract is more or less similar to the approved one for Quark Matter 2022, with some changes to reflect the already presented results. Thank you.
