STAR HardProbes PWG

Hello Dave,

Please find my comments on your nice presentation slides.


SLide-3:
_ '&' -> 'and' all places
_"Experimentally observe initial parton distribution: " -> Sounds 
awkward, if you refer to Slide 7and 8, then I would prefer "Measure 
quark and gluon fraction initiated jet"
_Measure parton shower increasingly differentially  -> Not clear what do 
you want to say?

SLide-4:
_Experimental data: particles in STAR -> "STAR detector" [as you have 
not discussed any data and run except detector]
_TPC particles  -> Charged particles from TPC
_TPC + BEMC particles -> Charged particle from TPC and neutral particles 
from BEMC

SLide-5:
_Field theory predicts observable -> Give reference. arXiv:2205.03414 , 
2209.11236
_"Observe/measure Λ_QCD" -> Do you mean we can measure 
"Λ_QCD" using EEC? Make it clear.
_ @ -> "At" or "For"

SLide-6:
_ Title: First corrected EEC measurement -> I recall these are not 
"corrected". Can you please confirm it?
_ GeV/c vs GeV/ italic{c} -> make it consistent at all places

SLide-8:
_Can you please remind me where do you get this preliminary plot?
_(data is moving to the right -> more quark dominated) ->it is not 
apparent. Can you point to me this preliminary results or previous 
presentation slides?

Slide-9:
_ I like right side jet cartoon. But it is quite unusual to have that 
many particles in pp jet even if it is a cartoon. Can you please make 
that with less number of arrows.
_ Make the equation size bigger so that visible to audience
_hot nuclear effects -> hot-dense QCD matter effect
_"Same results from measurement of jet girth" -> Better to be silent as 
you are not showing any results here. Opt to drop it.

Slide-13:
jets from -> jet yield from

SLide-14 and 13:
Introduce "EA"

Slide15
_ RAA -> R_AA
_ At RHIC kinematics -> Or "At STAR kinematics"
_ (3) jet in BBC ->  Do you mean "activity in BBC"? Not sure what is 
"jet in BBC"?
_ No "auto-correlation" from jets in EA acceptance -> Can you please 
explain what do you mean here "auto-correlation"?


Slide-16:
_ mid-pT and lower-pT ->  mid-p_{T}^{reco} and lower-p_{T}^{reco} 
_" 
Anti-correlation: EA distribution in high-𝑝T jet events significantly 
softer than EA distribution in mid-𝑝T and lower-𝑝T jet events" -> here 
this sentence is confusing. It is because of  "high-𝑝T jet events"  and 
"mid-𝑝T and lower-𝑝T jet events"; Can you please clarify it?
_And what is this <BBCE sum > for each pT^reco bins? Not clear.

_In side plot, 10< p_{Tiled}^{reco} < 15 -> 10< p_{Tiled}^{reco} < 15 
GeV/c; same for other two

SLide-17:
_"Qualitatively different from quenching in QGP in A+A collisions" -> 
Can you please expound what is the qualitative difference here between 
A+A and p+A?


Slide-20:
_ "Correlation results not from final state effects, but rather “new” 
physics present in initial configuration of the ions, or the initial 
stages of the collision" -> Not clear where do you get this conclusion? 
Can you please point to me which results you refer here?

I suggest to improve your summary slides 20-21. In the current form, it 
is a bit unorganized way summarizing your beautiful results and number 
of topics you covered in this presentation. Can you please give a try to 
improve it so that audience can get takeaway message ?



Cheers
Nihar
