STAR HardProbes PWG

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

Hello Tristan,

Please find my comments on your nice presentation slides.
_________
General comment/suggestion to all HP2023 and DIS2023 presenters:
1. Please make a Drupal page for all your preliminary plots and provide 
us the link.
If you have already done that, please send us the link.

2. While preparing your analysis plots for "STAR preliminary" request, 
please follow the guidance 1-7: 
https://drupal.star.bnl.gov/STAR/pwg/common/Preliminary-figures
It saves our time.
_________

Please increase your slide number font size and use different color. It 
is invisible.

Slide-2:

1. "The contribution of each process to jet quenching is unknown "-> But 
we do know in QGP radiative process dominates over collisional process. 
So this sentence probably needs to rephrase unless you want to say 
somethingelse.
2. Can you give reference for collisional E_loss's  L dependence?
3. For radiative case L^2 dependence comes from BDMPS. So you need to 
give reference.


SLide-3
1. In this plot, increase the X-axis title and label size (also for 
Y-axis). Not visible.
2. "Central events show significant hadron suppression at high momentum" 
-> "	0-10% central events show significant hadron suppression at high 
momentum"
3. You need to mention what are <Ncoll> and sigma_inel^NN and their 
values used for this result?

SLide-4

1. "Semi-central collisions produce an approximately elliptical QGP" -> 
"Semi-central collision produces a elliptical geometry of the QGP 
medium"
2.  "To use familiar language, we will report this as 𝑣2, despite jet 
quenching being being distinct mechanism from flow" Not sure what you 
want to say here.
3. I think you need to introduce what is v2 as 2nd order anisotropy in 
this slide?

Slide-6
1. X-axis title: pT^reco -> "pT^trak;
2. X-axis: increase title and label size; put unit
3. Y-axis: increase title and label size
4. You need to mention before or in this slide what is pT?
5. "No strong momentum dependence observed "  -> "No transverse momentum 
dependence of v_{2} observed at high-p_{T}"

Slide-7
1. "Measuring high 𝑝T charged hadron 𝑣2 gives us a connection to flow 
measurements " Not sure what you want to say? Why only "high-pT charged 
hadron v2 gives connection to flow"? Please rephrase
2. "…with resolutions …"  -> "…with resolution (R)…" here you can 
introduce jet R.
3. Give STAR paper's reference to this upper v2 plot.

Slide-9:

1. "2 GeV" -> "2 GeV/c"
2. "The event is clustered into jets with the anti-𝑘T algorithm" -> You 
have mentioned already in the above sentence. Drop this bullet.
3. "Δ𝑅 < R_resolution "  you need to find a better way to write this. 
What is R_resolution?
4. First subbullet of last bullet expression: you need to mention what 
are pT^measured, rho(phi), A, etc?

SLide-10:

1. Title: "Combinatorial Jet Quenching" sounds awkward. Please rephrase 
this. Something like "Combinatorial jet contribution"
2.   Put this slide in backup. If somebody asks then show. Otherwise you 
don't need to speak on this test.

SLide-11,12,13:
        1. Please follow the same suggestion on this fig from Slide-6
	2. "Small, non-zero R=0.2 anti-𝑘T jet 𝑣2 in isobar collisions at STAR " 
-> "Non-zero jet v_{2} is observed for R=0.2 in isobar collisions" (same 
for SLide12)
        3. "Like charged particle …" -> "Like inclusive charged particle…"
	4. "No obvious R dependence!" -> "No jet R dependence of v_{2} is 
observed"  (Not sure why it is "Obvious"?)

Slide-14:
1. Please follow  the same suggestion on this fig from Slide-6
2. "To remove correlations by comparing the same partons, the numerator 
and denominator are separate sets of events"
        Can you please rephrase this sentence to make it more clear?


Cheers
Nihar
