STAR HardProbes PWG

[Derek Anderson <derekwigwam9 AT tamu.edu>]

Hi Nihar,

Thank you for the feedback! I have implemented your suggestions in the version linked to below, and have a few responses in-lined below as well.

That's a good point! If I have some time, I'll experiment with some other ways of representing this, but -- given the late hour -- I may not have the time...

> "Observation of medium-induced intra-jet broadening" -> "First observation of medium-induced intra-jet broadening in heavy-ion collisions"

In my implementation, I left out "first" because I don't think that's quite true... As has been pointed out, STAR has observed medium-induced broadening before (c.f. Alice Ohlson's jet-hadron correlations).

Hello Derek,

Please find my comment and suggestions below on your nice presentation 
slides:

It is advised to follow the guidance for using roman vs. italic style of 
symbols.
https://urldefense.com/v3/__https://iupac.org/wp-content/uploads/2016/01/ICTNS-On-the-use-of-italic-and-roman-fonts-for-symbols-in-scientific-text.pdf__;!!KwNVnqRv!B3QtybmiuSMyj6JGjJw8eTXEzLS_DTo5M97Lpm9w-n7yyGIDKNRXVpH6GaLaCNKPilebHO5QxVvbaeHPw5HhHz4ca7I$ 
Note: it should be written as $p$+$p$ and $p$+Au, etc, which is 
different from the guidance


Slide#1
I think you could change your title:
"Reconstruction of neutral-triggered recoil jets in
𝒔 = 𝟐𝟎𝟎 GeV 𝒑+𝒑 at the STAR experiment"
->
How about
"Measurement of semi-inclusive pi0+jet and gamma+jet in p+p collisions 
at
𝒔 = 𝟐𝟎𝟎 GeV and its impact on heavy-ion measurement in STAR"
Or similar to this
(Because your p+p analysis is important for drawing conclusion that you 
show on your last slide; and you can make a link from your title
And people can wait until your last slide to know what is that impact)

Slide#2:
"Direct photon constrains kinematics of recoil jet" It is not clear; can 
you please elaborate or paraphrase?

Slide#3
Please mention what are these E_cluster, e_i, and r_i in this TSP 
formula?
Similarly, define all terms in direct photon yield formula below.
(People may be interested to know)

"E_cluster" -> "cluster" should be roman as it is a label and has no 
value.

Cosmetic suggestion: using these colorful cones at the bottom may 
confuse people as it may indicate also jet cone. So you need to use a 
different style to show "shower shape" by pi0 and gamma.

Slide#4

k_T -> make "T" roman style
"- With R = 0.2, 0.5" -> you can add this with upper sentence and remove 
"-" (Better reading in one go)
"UE effects small in 𝑝+ 𝑝" -> "Negligible effect of UE in p+p"

It would be better to add one sentence mentioning difference between 
Pt^reco, Pt^raw, and Pt^ch (which is x-axis in the upper plots). I 
understand this is difficult in limited space, for audience it is 
probably good to add.

SLide#5
"Different q/g fractions, path length distribution" -> I would prefer to 
drop this. Only upper bullet is Ok (" pi0 and gamma +jet iAA consistent" 
as you mentioned)

"…due to jet shape in vacuum"  -> "… due to vacuum parton shower "

"Au+Au suppressed relative to 𝑝+𝑝" -> "R^0.2/0.5 in Au+Au less than that 
in p+p collisions"
"Observation of medium-induced intra-jet broadening" -> "First 
observation of medium-induced intra-jet broadening in heavy-ion 
collisions"


Regards
Nihar
