STAR HardProbes PWG

[Diptanil Roy <roydiptanil AT gmail.com>]

Hi Nihar, I agree that we should not propose new preliminaries until we are confident in our results. Also, the paper proposal is coming soon. :)

Yes, I understand this. we have time to discuss this new FF results.
I will send my comment on your abstract in another email.

preliminary until you will have full confident on your new results or at
the stage of paper proposal.


Thank you
