STAR HardProbes PWG

[Yi Yang <yiyang0429 AT gmail.com>]

Hi Youqi,

Thanks a lot for the updated abstract and the presentation last week.

I only have two minor comments/suggestions for your consideration. 

  - L7: in ultra-relativistic collisions --> in particle collisions (?)   

  - Reference: should list it in the normal way as paper:  

A. Andreassen, P. T. Komiske, E. M. Metodiev, B. Nachman, and J. Thaler Phys. Rev. Lett. 124, 182001, 2020

Cheers,

Yi

Hello Youqi,

Your abstract looks in good shape.
I sign-off.

Regards
Nihar
