STAR HardProbes PWG

[Diptanil Roy <roydiptanil AT gmail.com>]

Hi Nihar and Barbara, thank you for your comments.

Nihar, we definitely need a lot more discussion on it, and I plan on updating Hard Probes PWG regularly with the analysis details. Since the meeting is in mid June, we have time to discuss. As for the fragmentation function itself, we are confident of the method, however, it needs to go through the review in the PWG.

Barbara, I agree with your comments, and we can definitely show the existing preliminaries, however the central values will shift, so I am not sure how to handle that bit. If that is ok, I can update the abstract to talk about spectra and radial profile as well. Since this is Initial Stages, I really want to focus on the fragmentation function, but I do agree that we might not have theory comparisons by then.

Please let me know your thoughts.

Hi Diptanil,

Thank you for this abstract.

I am a bit inclined towards what Barbara is pointing out.
and have also a little concern about the procedure that you just
discussed at collaboration meeting, we need more discussion on it.
We now knew that our QM2022 STAR preliminary results on D0+jet
will(have) change(d) based on your collaboration presentation.

Are you confident enough to show new FF on D^0+jet?
Please let us know.

Cheers
Nihar
