sPHENIX is a new detector at RHIC.

Dear sPHENIX Colleagues:

In ~180 hours, I will gave a talk titled “Exploring the sQGP with sPHENIX” at the ExploreQGP Workshop in Belgrade: https://indico.ipb.ac.rs/event/554/ . 

This is not an official sPHENIX talk, rather it’s my particular view of sPHENIX relevant to my research interests and tis workshop. I was invited to speak on whatever I wished to present, and I chose this particular topic. I have tried to use only official sPHENIX plots, and have taken most of the sPHENIX material from the beautiful recent talks of Anders Knospe and Weihu Ma. I welcome your corrections, suggestions, etc.

Some preemptive remarks:

The workshop is limited to 70 participants, but contains many of the usual suspects in our community. I want to make sure whatever I say about sPHENIX is accurate. 

The talk is 25’+5’ . Yes, I know it’s too long.

The organizers strongly suggest that the slides be projected from  a PDF file, not Powerpoint, in 16:9 format.

Remarks on specific slides:

14) The big white blank in the picture is to indicate the shield wall is in place; if anyone has a picture of the shield wall I would be very happy to swap it in. 

26) There is a reference that is attached to the standard sPHENIX plot in the lower right on this slide. I deliberately covered it up, because the figure is not in the reference.The reference points to an article by Martin Habich, Jamie Nagle and Paul Romatschke in which a parameterization for the time evolution of the medium is given. Jamie then used that information along with a Berndt Mueller paper to generated the curves shown in this plot. (Thanks to Jamie for explaining this to me.) The best reference for this figure is in fact the sPHENIX proposal. 

36) The event display is for iHCal and oHCal hits in real-data taking with a ~mid-central MBD trigger. This of course requires collaboration approval to show in public. I do not see a downside, but I am not in charge. I would of course be happy to replace/augment it with the “latest and greatest” right up to the time of the talk. (Thanks to the entire HCal crew in getting it commissioned and timed in, and to Oliver Suranyi for this particular event display.)

Best regards,

Bill
