STAR HardProbes PWG

[Nihar Sahoo <nihar AT rcf.rhic.bnl.gov>]

Hello Yuan,

Sorry for my late response. I have gone through PAs' responses to my 
comments. Thank you for that.
I have no further comments. It should move ahead.

We will be working on it to move this paper for GPC formation soon.

Best
Nihar
