STAR HardProbes PWG

[Youqi Song <youqi.song AT yale.edu>]

Hi Nihar,

Thanks for the comments. I have implemented them and uploaded a new version on drupal.

Slide4: "... and in a" -> Not sure if it has any meaning.

Here I am trying to emphasize that the two measurements shown on this slide are multi-differential measurements, as opposed to the inclusive measurements shown on slide 3.

Slide16: "this is a fake jet" -> "fake jet" is not a correct phrase this
context. You could use something else like "unused jets" . These are
true jet but you are not using in your r_c observable.

I still think this jet should be considered "fake" for the purpose of this analysis. The jet shouldn’t be included for rc analysis since at truth level, one of its leading dihadrons is a neutral particle. However, we won't be able to know that from data, so it ends up being incorrectly included for the analysis. I have added a sentence to explain this on the slide as well.

Best,

Youqi

Hello Youqi,

Thank your for your nice slides on jet substructure measurement.

Please find my comment below.

Slide4: "... and in a" -> Not sure if it has any meaning.
References are too small to see. For example "STAR. DIS 2021"

Make "CollinearDrop" consistent everywhere, Some places you write
"collinear drop". Please check this out.

Slide14:
"Jets with a more DGLAP-like splitting are more likely to have small
early-stage radiation" -> where did you discuss about "DGLAP"?  I could
not find.

Slide16: "this is a fake jet" -> "fake jet" is not a correct phrase this
context. You could use something else like "unused jets" . These are
true jet but you are not using in your r_c observable.

Slide17:
"..have a unique sensitivity for non-perturbative effects"  -> Trying to
understand what exactly you want to say here.
This slide you may end up with some open questions or a bit generic. Up
to you.


Cheers
Nihar
