STAR HardProbes PWG

[Tristan Protzman <tlp220 AT lehigh.edu>]

Hi Rongrong,

I have managed to throw together a quick v2 on part of the data down to 0.5 GeV, see slide 16 of https://drupal.star.bnl.gov/STAR/system/files/preliminary_figure_request_OO_v2.pdf.  I believe the open blue squares in Shengli's results are the closest method to what I am using, where we see general agreement interpolating between the 20-40% and 40-60% with the non-subtracted EPD based method.  

Cheers,

Tristan

Hello Tristan

I would like to follow up on the comment I brought up during the PWG meeting about the single track v2, which if I remember correctly is about 0.15 at 4 GeV/c. On the other hand, slide 9 of https://drupal.star.bnl.gov/STAR/files/OO-ShengliHuang-QM2023_2.pdf shows that charged hadron v2 is about 0.075 at 2.5 GeV/c in 20-40% centrality. Have you looked at single track v2 down to say 2-3 GeV/c, and check if your results are consistent with Shengli's? Or at least we should put both results together and see if we have a consistent picture. 

Thanks. 

Best

Rongrong
