STAR HardProbes PWG

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

Hello Youqi,

Please find my comments and queries on your nice slides.

Slide3:
Use “𝑔 ” -> it looks eerie in this way, you could mention "subscript 𝑔 ”

Slide7: "Note: Hadronization effects smear the distribution but don’t 
affect the correlations" and backup slide-28
In the backup slide, what is "PYTHIA No hadronization"? Do you mean you 
check the effect of harmonization comparing parton level and with 
hadrons using PYTHIA?
I forgot this discussion, can you pleas remind me again? Thank you
_ you could show lower bottom plot of slide28 in this slide.

Slide11:
Please provide reference to these expressions like formation time and z.
Mention what are t_1,2,3 in side the plot? And what are 50, 200, 800 
here?

_Can you make similar right 2D-plot (zg vs Rg) for pp data ?


Slide12:
Interesting!
This discussion mainly based on HERWIG.
I see now this "What will data tell us? Stay tuned! "
I would make it Bold and bigger, place somewhere people can see this. It 
is lost inside. [same on Slide11 too]


Slide15:
-In the future, potentially measure this in heavy-ion collisions! -> I 
have been seeing this but never commented yet. But I think in heavy-ion, 
it would not be that easy. So better to be cautious on this statement.


Slide18:
Weak dependence on jet 𝒑𝐓 -> probably not correct or difficult to say 
because: 1) depend on jet selection (hardcore vs inclusive jet 
population) 2) we don't show full jet pT range, say below 20 GeV/c.
Suggestion: either remove it or mention what jet population and within 
jet pt range.

Not related to your this presentation:
As you have seen Charles presentation on r_c vs formation time plot. 
Could you make similar plot for your analysis to see what is the trend? 
We can discuss at hp-pwg in your next presentation if you could.


Thank you
Nihar
