Hello Huan

Thanks for providing me your comment, which is a good point. I have updated the slides at the same link: https://drupal.star.bnl.gov/STAR/system/files/RMa_CFNS_npQCD_v3.pdf. I added "within uncertainties" on slide 5, and significantly weakened the statement on slide 26. 

Please let me know if you have any further comments. Thanks.

Hi Rongrong,

  It is a nice talk and I enjoyed reading it.

  I wish to raise an issue regarding HF electrons result at 27 GeV on slide 5 and the conclusion on slide 26. Slide 5 stated the HF-e v2 consistent with zero and the conclusion stated no strong slow at 27 GeV. But the data on slide 5 are consistent with BOTH no flow and the same flow magnitude as 54 GeV. So I do not think these statements are justified. I have not seen any experimental signatures that the QGP at 27 GeV would have drastically different properties as those at 54 GeV although the yield of heavy quarks would be smaller. I would be more comfortable with a statement that we do not have enough statistics of HF measurement at 27 GeV to be definitive about the HF characteristics in QGP at 27 GeV.

  If there are other experimental data support your conclusion, they should be mentioned before you reach these conclusions.

  Thanks. Regards,

  Huan

Dear All 

 

I was invited by the CFNS-npQCD workshop (https://indico.cfnssbu.physics.sunysb.edu/event/110/) organizers to present an overview of the STAR heavy flavor results. Even though it is not a STAR talk, I will exclusively present STAR results. So I would like to seek your comments and suggestions on my talk, a first draft of which can be found here: https://drupal.star.bnl.gov/STAR/system/files/RMa_CFNS_npQCD_v1.pdf. 

 

Your feedback is more than welcome. Thanks.
