STAR HardProbes PWG

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

Dear Sooraj,

Thank you for addressing my comments.
Please find below my additional comment and reply to your questions.
I sign off with this minor implementation.

Slide13- “intranet” -> intra-jet

> what do you mean by production mechanism of mesons?
Production mechanism in pp vs AuAu.

Yes, we can do it without HFT in pp.

Yes, but we can also lower D0 Pt below 5 GeV/c inside a jet.
That is what our outlook was ,AFAIK.

Best of luck for your presentation.

Regards,
Nihar
