STAR HardProbes PWG

[Sooraj Radhakrishnan <skradhakrishnan AT lbl.gov>]

Dear Nihar,

   Thanks for the review and the helpful comments and suggestions. I have implemented them in the new version. Please see. Please also find some responses below

//Slide#2

_ "microscopic mechanism jet suppression in QGP" -> not clear what is 
microscopic mechanism? please rephrase it.//

----- Done

//_ "Jet substructure dependence of suppression " -> "Modification of jet 
substructure"//

------ This was following the BUR proposal that jet substructure can be used for triggering and thus study the modification for different kind of jets. I havent changed, but let me know if the phrasing is good

//Slide#10:
You could also mention in Isobar analysis "high pT charged particles 
with pT > 5.1"//

------- Done

//slide#11:
_I think this IAA plot is good to show.
_But, main result in this analysis is "medium-induced Intra-jet 
Broadening"
And this is our first clear observation in STAR (Please highlight this 
result).
You could consider to add that Ratio plot in another slide or merge 
these two results in one slide.
And please mention in your summary slide#19.
Please have a look at slide#17.
Derek's QM2022 
talk:https://indico.cern.ch/event/895086/contributions/4717079/attachments/2421604/4145053/AndersonTalk_QM2022.v11_manualAnimations.pdf//

------ I have added the ratio plot as a separate slide, please see

//Slide#12:
In Title, please remove "intrajet broadening and Acoplanarity" -> 
"Medium-induced jet Acoplanarity"
Because Intrajet broadening and acoplanarity are two physics and you are 
showing latter.//

------- I had kept the same title for all the three slides as they are related physics 

//Slide#13:
_ "Study HF jets to better understand the mechanism of redistribution" 
->
"Study HF mesons in jets are sensitive to the production mechanism of 
mesons, energy loss and diffusion of heavy flavor quarks in QGP."
_ "D0 jets " —> please use either "D0 within jet" or "D0+jet"
_ "higher statistics p+p dataset in 2024 " I would not mention this 
because we don't have HFT for future runs.
_  You can mention that we are working on to lower the D0 pT range.//

-------- I was focussing here only on the broadening part and what HF jets can provide in that regard. I understand the general motivation, but would prefer to keep it brief here. I have added a back slide for the Rcp. Also, what do you mean by production mechanism of mesons?
-------- I saw the improvement of statistics for p+p being mentioned in Diptanil's QM talk, so added. I think even without HFT, with the higher statistics, we can improve on the existing p+p measurements 

------- How much lower in pT do you expect to go with D0 tagged jets? Currently its 5 GeV/c, isnt it the lowest jet pT we go in STAR, other than for the semi-inclusive measurements perhaps?

//Before summary slide:
You could show the STAR HardProbe program's past, current, and future 
kinematic coverage:

------- Thanks for the suggestion, added

thanks
