STAR HardProbes PWG

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

Hello Yang,

Thank you for posting your slides.
Although we can discuss in details about the results on Tuesday.


Please find my comments below.

1. Why do you cut your recoil jet pT spectrum at 5 GeV after unfolding? 
Where you showed your closure test work even at very low jet pT upto 
zero?
2. Why have you use detector level track pt cut < 25 GeV? Have you used 
the same track pT cut on particle level in PYTHIA events when you make 
response matrix?
3. Your jet matching efficiency shows there is a sudden drop at 25 
GeV/c. Which might be because of my concern in 2. Then In that case I 
would not trust jet pT above 25 GeV/c. And It needs further 
investigation, and for HP2023 we don't have time. So let's plan to show 
upto 25 GeV/c.
4. I don't understand you higher jet R especially 0.4 and 0.5 results. 
When I look at your slide-27 and 28, after ME subtraction, 0-10 and 
60-80% look reasonable. But I didn't  see any intermediate plot like 
after unfolding how they look like? Before and after unfolding 
comparison. IN this scenario, I would suggest to concentrate on and plan 
to show at HP2023 only jet R=0.2 and 0.3 results. Then we can get time 
later to investigate on it.


Cheers
Nihar
