STAR HardProbes PWG

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

Hello Andrew,

I found time today to go through your nice paper draft on EEC 
measurement in pp.
As I am a pwg representative of your paper, I have to go through again 
during GPC.
So, Here I just have some quick comments, details I may give during GPC 
discussion.
With these address, I sign off.

________________
1. Abstract is too long.  "no more than 600 characters".

L25: quantum chromodynamics (pQCD) -> quantum chromodynamics (QCD)

L30: "called a jet. Substructure…" You can make another para with "Jet 
substructure …"
Or, from "Recent…"
L35 : "…including its transition from a perturbative to non-perturbative 
scale." -> you need to mention what is this transition in QCD? And what 
is the scale? Not clear for general readers.

L40: "re-lying on advancements such as …" -> sounds incomplete 
"advancements of '…' such as" ?

L40: if we could mention what are "perturbative portion" and 
"non-perturbative information"? Then that would be good for general 
reader.
L50: N-Point -> N-point

L55: need to define "angular (distance) scales, R_L"?
L95: Λ_QCD needs to be introduced before. Right place is L35.
       Also P_T,jet
"to lower angles" -> Not clear what angle?
L120:  before this line, Better to mention intigrated lumi of this 
dataset.
L135: "with this energy never allowed to go below zero." -> you mean to 
say that if it is below zero then you don't consider that tower in your 
full jet reconstruction. But the energy of tower after subtraction may 
go to zero practically. Is not it?

L160: "RL is the angular distance between the two tracks in the pair." 
Here you are defining again. See L55 comment. Make it consistent.

Section.III
_ Is this PYTHIA6 a STAR tune?
_We need to mention P_T,jet resolution for these three P_T,jet ranges.
_You did not discuss about the closure test for this correction 
procedure.

Summary Section.V
I would suggest to concise this summary section for PRL so that reader 
can get the crisp/key points of this measurement.
Some discussion and conclusions can be included in Result Section IV.

Fig.2,3-> Please increase the label, Title, legend font size

In these figures, are these quoted  pt,jet ranges from PYTHIA or the 
data?; if these are corrected data, then it is ok. Otherwise we need to 
discuss in GPC.


________ANALYSIS NOTE_

-page 5/38:  what is the time line to update pertaining figure in this 
analysis? As we are going to GPC, it is important to know. how much that 
will affect the final plots?
[same for the other places]


Best
Nihar
