STAR HardProbes PWG

Hi Youqi,

Thanks a lot for the nice paper draft and analysis note. I am sorry it took me a bit of time to go through them. I think they are in very good shape and I have no problem letting this nice analysis move forward. 

I have some minor questions and suggestions for your consideration while we are forming the GPC:  

 - L167: you mention since UE/IRS/pileup is not significant, so you can choose "less aggressive grooming criterion", but it seems to me still a bit random, why not 0.2 for z_cut,2 for example. Do you have any reason for choosing these two sets? I think I asked this many times, but I remember the answer is this is what you normally did? The other question: will your conclusions change if we choose different sets? (How stable is it? Probably I missed in the draft).   

 - L277, 278: x% and y%  will be updated with new embedding, right? If so, it would be good to have some numbers here.    

 - L316, 317: ?%: Similar as above.  

General comments on Figures: I would suggest adding more descriptions in the caption. For example, Figure 1, it would be good to mention the green dashed line is PhythiaXXX and the band is NLL SCET... Figure 3, it would be good to mention what 1, 2, 3, 4 means (agaion) in the caption.

Question: Are you planning to have another longer paper for this analysis? When I read the analysis note, I found many interesting details probably worth to be public. Just a thought. 

Cheers,

Yi

Hi all,

Please find my paper draft and analysis note here and let me know if you have any comments or suggestions! I plan to request for GPC formation during the collaboration meeting. Here is the drupal page:
