Hello Grant,

Please find my comments on your nice presentation slides.
I like your Slide#5,13,14 Pythia jet charge plot. Are the κ values the 
same as your pp data?


Slide2: Just a comment on your right side cartoon. Is there any 
relevance of showing jet2,3 in opposite side to your jet charge 
measurement?

Slide3: Infrared, collinear safe -> Infrared-collinear safe or Infrared 
and collinear safe

SLide4: "The energy loss in AuAu collisions depends on the flavor of 
parton" -> It seems out of the context here as you are focusing on jet 
charge in pp collisions; you could mention one motivation for heavy-ion 
collisions related to jet charge. Is not it? (Comment: so far no 
modification in jet-charge is seen in heavy-ion—at least at the LHC)

Slide5: In plot: mention what collision energy and p+p collisions, etc? 
Is this the same "κ=0" value used in the data?

Slide8:
_Make your y-axis label up to -0.1 so that lower cutoff data points can 
be visible (similarly for other plots)
_ Please mention what "κ" value is used? Better would be in legend

Slide9:
_Give reference of RooUnfold;
_right slide plot, X-Y axises title should be jet pT (please make 
changes).
_Q depends on pT -> Q depends on jet pT
_Requires 4D response -> Requires 4D response for 2D unfolding

Slide10: Do you think it would be good to show semi-log scale (y-axis) 
for right side plot? So that all systematic contributions can be visible 
clearly. In the linear scale Hadronic corrections, not see at all.

Slide11:
_Make your y-axis label up to -0.1 so that lower cutoff data points can 
be visible (similarly for other plots)
_ Please mention what "κ" value is used? Better would be in legend

Slide12:
"Mean shifts to from ~0.22 to ~0.33" -> Do you mean with increasing jet 
pT window? Then rephrase "Mean shifts from ~0.22 to ~0.33 with 
increasing jet pT"
_ Please mention what "κ" value is used? Better would be in legend

Slide13:
_If your  "κ" value is different than that you used in data, then it 
would be good to have a comment/statement on it.
_ Can you please elaborate "Normalized Templates" ? Do you it is 
normalized per jet?

Slide14:
_ Can you please elaborate "Fit results" ? Have you done any fitting 
with the data on slide12-13? It needs some explanation here.

Slide15:
_Not clear "Different jet resolution parameter R values"; please 
explain.
_Provide constraint on quark vs gluon fraction value to improve 
simulation - > do you really mean to improve "simulation" here?


Cheers
Nihar
