STAR HardProbes PWG

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

Hello Veronica,

Please find my comment and suggestions on your nice poster.

Introduction:

_Yet ATLAS (right) and PHENIX ..   ->  ATLAS and PHENIX … (please 
provide references to these results)
_"WHy ?" Remove it

_"p+A collisions thought too small for QGP formation "  Need to mention 
what that is "small"? For example, system size, initial energy density, 
etc

_"How does the hard scattering in an event affect event activity (EA) 
and underlying event (UE) at mid-rapidity?" -> You need to mention what 
is EA and UE.

_Just after the above statement.
This ATLAS plot does not fit to the physics message.

Experiment and Event Activity:

_Mention what is eta?
_"|η|<1, " - > "|η| < 1 " (similarly below) 
_ "Charged tracks …" and 
"Neutral tower…" in box; please include in the TPC and BEMC bullets (no 
need to have a separate box)
_"the inner BBC signal" -> what is that signal? ADC/hit/ etc.


Jets and UE measurement method:

_R=0.4 -> mention what is R?
_ Need to mention what are  phi_lead, phi_trig, phi_UE, eta_lead?
_what is p_{T,lead}^{reco}? Mention it.

Jet mass as a function of EA:

_Define and mention what is jet mass?
_Consistent with QCD predictions and STAR pp data  -> "Consistent with 
QCD predictions" or "STAR p+Au data and QCD predictions are consistent"


Activity-dependent jet yields:

_"The distribution of EA_BBC is inversely correlated to leading jet pT" 
and also its bullet -> Please rephrase this; not clear


Conclusion:
"Dependence of soft particle production on the initial hard scattering" 
-> How do you draw this conclusion?
"Indicates EA vs. Q2 correlations from early time effects" -> Not sure, 
How do you draw this conclusion?
"Jet quenching in p+Au collisions disfavored—no sign of final state hot 
nuclear matter effects" Very strong statement. I would suggest to drop 
this or mild this statement. Not sure how do you get this conclusion?


Cheers
Nihar
