STAR HardProbes PWG

Dear Convenors and all,

I received the following comments on my SQM proceeding. I implemented most of those and uploaded V5 in the same node as previous one. https://drupal.star.bnl.gov/STAR/node/68859

Please find my responses to these comments and questions.

Abstract: particle emit and the -> are emitted and on the  ---> DONE

Abstract: Such correlations ... in the hadronic phase. -> this sentence has to be rephrased in the sense of clearly stating that the correlations can bring information about the interaction of charm quarks with the QGP medium and of charmed hadrons in the hadronic rescattering phase. ---> I am not sure if I can make this statement as we don't have any theory model which can connect the findings through femtoscopy at final state can connect the interaction at initial stages, so kept the line unchanged

page 1: In the early ... establishment [1]. -> Heavy quarks such as charm (c) and its charge conjugate (c-bar) are created in the early stages of ultra-relativistic collisions of heavy ions. Therefore, they probe all stages of the evolution of heavy-ion collisions - Quark-Gluon Plasma (QGP), hadronization, chemical and kinetic freeze-out.  ----> DONE

page 1: remove the sentence with the big bang. It is not really linked to the rest of the text.   —-> DONE

page 1: interact with the medium -> which medium? QGP? Than clearly state it    ----> DONE
page 1: paarticular -> particular   -----> DONE
page 1: Phase... [5]. -> Phase-space evolution of emission source and final-state interactions can be both studied with such measurements in heavy-ion collisions [5]. ------> DONE
page 2: suggest to remove the branching ratio -> Kpi. Moreover, 'and set of topological criteria' is somehow not linked to the rest of the sentence -> rephrase   ------> DONE
page 2: Fig.1 shows the reconstructed D0 and D0-bar invariant mass distributions using STAR data of Au+Au collisions at sqrt(s_NN) = 200 GeV [4].   —---> DONE
page 2: remove 'for this study'   —----> DONE
Figure 1:

) you have purity labels, but you do not discuss them at all. So either remove them or quote them later on where you explain Eq.(2). It is better maybe to remove them , because in these plots you show only D0 candidates, while you refer to the purity in terms of D0-identified hadron pairs. If in the figure you quote the D0 purity, write it clearly in the caption and/or in the text.   —--> I mentioned about D0 purity right above the fig 1, this comment is unclear to me

) Add Au+Au, sqrt(s_NN) and STAR label   —---> Can I put "STAR" in the inv mass plots??

) red curved should be added to the legend  ----> Not yet implemented

) caption: you discuss here for the first time the LS pairs. This should be properly addressed in the text. Moreover, it is not clear whether the red curves are a result from the LS subtraction, or just results from the fitting procedure. Note also that the black points are US, but what happens is that the US background can be described well with LS pairs. Please revise the caption and the corresponding text to avoid confusions.   —---> Modified 
page 2: The computed value of the correlation function can be affected ---> DONE
page 2: identifying -> identified  -------> DONE
page 3: 'to reduce contamination ... present in the system' -> this is a bit hard to ready, if you can please rephrase to make clearer.  ---> DONE
page 3: n-sigma -> you have to explain that you discuss PID here and describe what is it.  ---> Rephrased with a reference, but looking for a better reference
page 4: Theory calculations... pairs [9]. -> Please write properly that in the left panel the theory predictions are for a mixture of D0-pi+ and D+-pi0 and in the right panel for D0-K+ pairs.  -----> DONE
page 4: what do you mean by 'at the origin'?  -----> Modified

The reviewer informed me that they intend to finalize the proceeding by Dec 3^rd but I received the comments not much earlier. So, apologize for the last moment rush.

Please let me know if you have any questions and comments to address.

Regards,

Priyanka
