sPHENIX cold QCD topical group

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

Hi, Joe.  Thank you for representing cold QCD at sPHENIX at Quark Matter along with everything else you’re currently doing for sPHENIX (and PHENIX, and finishing up your thesis!).

 

The large panel on gluon spin looks a bit out of place for QM.  It would be good to discuss nuclear PDFs more given the audience. Unfortunately we don’t have many sPHENIX plots on nuclear PDFs to provide visual material for a poster, but here are a few things you could consider.

 

Change the “Jet Measurements” section to “Nuclear Modification of Parton Distribution Functions and Hadronization,” then focus on the different ways to constrain them.  Add a nuclear PDF plot, e.g. the EPPS16 one we have as Fig. 1.3 in the barrel ME document.  Then you could add text similar to the following (spliced from the barrel ME document):

 

“The sPHENIX barrel will improve our knowledge of nuclear PDFs via measurements of inclusive hadrons, jets, γ-jet correlations, dijets and Drell-Yan in p+A compared to p + p collisions. These data taken together will cover an x range from several times 10−2 for inclusive hadron measurements up to ~0.4 as shown for dijets.”

 

Keep the dijet x1, x2 figure and point out that it’s also relevant for p+A, e.g. you could add “in p+p and p+A collisions” after “a large range of x.” 

 

You could remove the azimuthal asymmetry plot and replace it with material on hadronization.  (If you add the nPDF plot you’ll still have two plots in this part of the poster.)  Again grabbing from the barrel ME document,

 

“Hadron-in-jet, γ-jet, and dijet measurements multidifferential in momentum fraction z of the jet carried by the produced hadron and in jT, the transverse momentum of the hadron with respect to the jet axis in p + p. These jet profile studies will provide information on hadronization within a jet, and γ-jet and dijet measurements will provide different mixes of quark and gluon hadronization.”

 

And you could mention how comparison of jet profiles in p+A vs. p+p will provide information on nuclear modification of hadronization.

 

Instead of the gluon polarization panel, you could discuss heavy quarkonium production, in particular upsilon polarization measurements and how they relate to the production mechanism.  For a visual you could show Fig. 3 from Cheung + Vogt, PRD96, 054014 (2017) (https://arxiv.org/pdf/1706.07686.pdf) that predicts a large longitudinal polarization at sqrt(s) = 200 GeV in the CEM.  You could also mention the pT spectrum, and J/Psi in addition to upsilon.

 

Depending on how the space allocation ends up, you could consider expanding the forward upgrade panel, adding Fig. 1.4 from the forward LOI on the x-Q2 coverage for DY. 

 

Definitely keep the panel on Evolution to an EIC Detector—this is important to advertise at QM!

 

I’d also suggest adding the public URLs to the references for the document describing medium-energy physics with the baseline detector and the forward LOI:

 

Medium-energy physics with baseline sPHENIX:

https://www.sphenix.bnl.gov/web/sph-cqcd-2017-002

 

Forward instrumentation LOI:

https://www.sphenix.bnl.gov/web/node/450

 

And as a very minor comment, ‘barrel’ isn’t capitalized in the references.

Dear Cold QCD group,

 

Apologies for the email spam, after Dave Morrison's email last night I have updated the poster to conform to the sPHENIX guidelines. I have uploaded my poster draft file to the indico page:

 

https://indico.bnl.gov/event/4604/

 

Any comments or suggestions would be appreciated.

Dear all,

 

I modified the poster to fit the Quark Matter '18 size regulations, and additionally added the up-to-date EIC detector model per Nils' request. Please find the updated draft at the following link:

 

https://www.dropbox.com/s/m8qki2e3jdouci0/QM18_cQCD_sPHENIX_Poster_d01.pdf?dl=0

 

The previous link that I sent earlier won't reflect the updated changes, as this has the old poster that didn't conform to the Quark Matter size.

Hi Nils,

 

Thanks for this, I was also just notified by Raghav that QM has a poster size limit which is portrait style, so I'll have to modify the formatting. However, the content will remain mostly the same.

Hi Joe,

 

I'll read it later, here just an immediate comment: please use the much more recent detector illustration for "EIC-sPHENIX" from the top of our wiki page

Dear sPHENIX Cold QCDers,

 

I will be giving a poster for the sPHENIX cold QCD physics program at Quark Matter 2018. The PDF file is attached to this email.

 

Any comments and/or suggestions by Monday, May 7th would be appreciated as I plan on printing the poster on Tuesday, May 8th.

 

Thank you,

 

Joe Osborn
