sPHENIX cold QCD topical group

["Aidala, Christine" <caidala AT bnl.gov>]

Hi, John.  

p. 9 - Perhaps it's intentional, but the slide doesn't make it clear which 
rapidities would be needed for the observables listed.

To make the "p-shine (unpolarized)" clearer, you could write "p-shine: gluon 
impact parameter distribution in (unpolarized) Au nucleus via J/Psi"

"Au-shine: access GPD E_g in (polarized) proton via ..."

p. 17 - The 11-panel plot is extremely difficult to read.  Even though it's 
written on the STAR plot, I'd suggest explicitly writing the observable for 
the panel plot, as well as arrows indicating that jet pT is increasing from 
left to right, and jet pseudorapidity is increasing from top to bottom.  You 
might even consider removing the top three panels, since on the vertical axis 
range shown, you can't really see if we can learn anything or not.

p. 18 - I'd put a comma after "causality" to help people read this smoothly.

Presumably what you say verbally will make the main messages of this slide 
clear, i.e. that sPHENIX and in particular fsPHENIX will provide important 
information on the initial state / early stages of A+A collisions, on the way 
to an EIC.  If you want people who miss your talk but look at your posted 
slides to get this message, you'll need to put it on the slide.

Enjoy DIS!
Christine

Hi John,

a very nice talk as always. I have one suggestion on page 20: You mention the 
spin dependent fragmentation which is of course relevant, but the main goal 
of the Collins measurements is the quark transversity and in particular the 
tensor charges. The h- (as pi- proxy) Collins measurement would give us an 
increased x reach at relatively high scales of the d quark transversity in 
particular.

Since you mention the cold QCD plan and the workshop we held last year, maybe 
you could also advertise the next workshop this June as people might be 
interested in it:
RBRC workshop on Synergies of pp and pA collisions with an Electron-Ion 
Collider from June 26 - 28 2017 at BNL https://www.bnl.gov/pppa17/

Cheers,

Ralf
