STAR HardProbes PWG

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

Hello Isaac,

Thank you for sharing your DNP overview talk. It covers nicely all 
subject on HotQCD STAR-jet physics.
Have you checked the time duration of this talk?

Besides, find my comments for your consideration.


Slide15: "Observe also in ALICE: …but tension with models at high kT for 
narrow splits" Is this true for STAR also? If not, please add a text 
there about STAR observation.
For ALICE plot: if you could show ln(R/DR) plot that would be more 
informative. Then you can show one slice of ln(kT) plot.
[just for your consideration]

Slide14:
Would it be interesting to point it out why on slide15, "tension with 
models at high kT for narrow splits" and on groomed mass case "MCs are 
in good agreement."? Do we understand here why this is the case?

Slide17: "Consistent with time evolution to non-perturbative regime;" -> 
is not that "Consistent with time evolution to perturbative regime;" 
like Altarelli-Parisi evolution Eq. That is pQCD at least 1st splitting?

Slide19: "With conservative systematic uncertainties in biased pop., no 
modification in AA observed"
We know Tanmay is working on it and knowing this result was very last 
time approved for QM23. I would prefer not to sell it as "no 
modification in AA"; Could we be a bit silent at this moment? What do 
you think? Just mentioning within uncertainty pp and AA are consistent. 
Period.


Slide21: What is "R_L" here?  "NP" -> non-perturbative or npQCD

Slide23: Have we shown STAR EEC plot with x-axis "<p_T,jet>Delta_R" as 
STAR preliminary? Probably I missed that.
              What <p_T,jet> we use in our STAR plot? And is that 
corrected?

Slide29: lower right plot needs reference (the guy, who made this, will 
feel good and need some citation :))
On this plot, you circled it, and you could also highlight why in 
inclusive jet case we don't see jet R dependence unlike other cases?

Slide39: left side plot needs reference

Slide40: "Possible sign of jet diffusion wake: enhanced baryon-to-meson 
ratio in AA" -> After Reading this paper, what they mainly conclude 
because of "via parton coalescence" not exactly diffusion wake. 
Enhancement in b-to-m ratio should come from hadronization chemistry.
So I would prefer to write "Possible sign of parton coalescence in jet". 
If you agree.


Best
Nihar
