STAR HardProbes PWG

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

Hello Andrew,

Please find my comments on your nice presentation below.
___________
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.
_________

SLide:-2
t_f : mention "formation time"

SLide-5:
In plot:
Legend shows all blue, red, green markers are 15-20 GeV/c jet pT. I 
think that is not the case. Please correct it. (Slide6)
As this is a PYTHIA study, I would strongly suggest to use open marker 
here.
Because you have used the same marker style while plotting the data. 
Otherwise it may confuse the audience.

Each dashed line:
Have you used the expression "Lambda_QCD/jet Pt" to find the value of 
Delta_R in the left plot?
If not, can you calculate what is the value if you use "ave jet pT" of 
these three cases?

Slide6:
"< 𝑝𝑇 𝐽𝑒𝑡 >*∆𝑅𝑇𝑢𝑟𝑛𝑜𝑣𝑒𝑟 ~ 3.6 GeV" Not clear to me what this "3.6 GeV" 
implies here?
Where do you get "DeltaR_turnover"? Have you calculated as I mentioned 
above? Or just by eye?

SLide7:
"Experimental Measurment at STAR" -> "STAR detector" (all measurements 
are experimental) (same on slide8)
You could show other colorful STAR detector pic.
"Must correct for inefficiencies …" ->" 	Must correct for detector 
effects…"

Slide9
Mention what is "DeltaR_jet" and "DeltaR_track"?
Both left and right slide, X, Y axis labels are too small. Please 
increase the size.
Put Unit on both the axises.

Slide10
Both left and right slide, X, Y axis labels are too small. Please 
increase the size.
Put Unit and title on both the axises.

"..do not need to correct additionally to 𝒑𝑻𝑱𝒆𝒕 " -> I this we don't 
need correction for EEC but "pTjet range" needs to be corrected. Is not 
that?

Slide17:
"quark/gluon region continues longer before geometric cutoff" -> do you 
understand why it is so?


Cheers
Nihar
