Hi Isaac,

Thanks for the comments, please find my responses in line.   I've uploaded a new draft also containing Helen and Yi's comments. 

Cheers,

Tristan

Hi Tristan,

Good to see a rough consistency with your results and Shengli’s. I have a few small comments on your poster below, and sign off.

Thanks,

Isaac

Overall the beginning half of the poster especially is a bit on the jargon-y side. For non-experts, it could be nice to define the event plane, pT, \rho, etc. [Apologies if I missed any of these definitions.]

Added quick definition of event plane as defining the orientation of the collision and rho being the average background density

I was going to make a comment on the third bullet: "Thus, due to quenching, the expected...". I see now in the next bullet you have a distinction between flow-driven and quenching-driven, so maybe you don't want to introduce quenching at the point of the third bullet, but in that case you should just drop the "Thus" since it doesn't follow necessarily from bullet 2 alone.

Rearranged this slide a bit, please let me know if you think this is clearer.  

"\rho modulated with assumed..." is cut off by the plot.

Moved details of rho modulation to isobar jet v2 results

"E_T > 3.4 GeV" -> "E_T^trig > 3.4 GeV"

Changed

"No strong jet resolution parameter dependence

Removed this statement since I have a whole box on it later

I think you should go into the ATLAS results a bit. You have some white space there so you have room to give one or two sentences about the hypotheses they have in that paper for this behavior.

Will look into this, but as you saw the state of the OO results is a bit in flux right now so I'll let you know when I return to this point.

It could be good to give an outlook about how fragmentation/geometric bias will be addressed in the future.

I would love to but I think I'm running out of space in the summary slide :)

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
