sPHENIX cold QCD topical group

[Alexander Bazilevsky <shura AT bnl.gov>]

Hi John,

A few comments/suggestions to you talk:

9: "Au-shine (polarized)": for me it is a bit confusing; may be add "p-polarized"?

10: I'd use "50-100 mkm" resolution for GEMs instead of "50 mkm"; first, this is exactly what we quoted in our fsPHENIX proposal, and second, it may look less challenging (and less unreachable).

12: This is not the first time when I'm confused with these plots not showing what rapidity they correspond to (despite that the next slide shows it); actually I agree with Abhay to remove this slide.

19: Should you explicitly point on the plots that they are for 200 GeV?

22: Directions for e and p/A are wrong; swap them.

23: Probably for ePHENIX picture the more relevant reference is 1409.1633 ("eRHIC design study"), you may take the title page from there.

Regards,

Sasha.

Dear Cold QCD'ers:

    I was asked to give a talk on sPHENIX/fsPHENIX at DIS this week; the talk is titled "The sPHENIX Detector:  The Future of Heavy-Ion Collisions at RHIC, and a Foundation for an EIC Detector" (abstract included at the end of the email).  A draft of the talk is available at:

(PDF) https://www.dropbox.com/s/a9roz2xagdwm48o/sPHENIX_DIS2017.pdf?dl=0

(PPT) https://www.dropbox.com/s/956hd5tt03f63i0/sPHENIX_DIS2017.pptx?dl=0

This talk has a lot of ground to cover, and it is listed for 20 minutes (so I'm assuming 17+3). The abstract was sent in prior to the ALD's call for a letter of intent, so somewhat fortuitously it seems rather timely.  I want to briefly introduce sPHENIX and showcase the recent progress, end with the EIC detector, and spend most of the time in the middle talking about fsPHENIX.

The talk is Wednesday at 16:40 local time in Birmingham, U.K.  Comments and suggestions would be greatly appreciated! As you can see I am likely a little long, so it would be great if suggestions for additions were accompanied by suggested deletions. ;-)

Regards,
John Lajoie

Abstract:

The sPHENIX Detector:  The Future of Heavy-Ion Collisions at RHIC, and a Foundation for an EIC Detector

The 2015 US Nuclear Physics Long Range Plan called for a state-of-the-art jet and upsilon detector at RHIC, called sPHENIX, to study the microscopic nature of the Quark Gluon Plasma in Heavy Ion collisions, complementing similar studies at the CERN LHC. The sPHENIX detector will provide precision vertexing, tracking and full calorimetry over pseudorapidity |eta| < 1.1 and full azimuth at the full RHIC collision rate, delivering unprecedented data sets for jet and upsilon measurements at RHIC.  In the same Long Range Plan, an Electron-Ion Collider was recommended as the highest priority for future construction.  The EIC will allow for precision measurements of the partonic and spin structure of hadronic and nuclear matter using e+p and e+A collisions. In this talk I will present an overview of the sPHENIX detector design, expected construction and running schedule, and planned physics program. I will highlight the possibility to complement sPHENIX with additional forward instrumentation for spin polarized p+p/A physics and the potential to evolve sPHENIX into a spin polarized e+p/A detector at a future EIC.
