sPHENIX is a new detector at RHIC.

Hi Dennis,

See below for your suggested change. I had a question though:

“ change “first two years of running” -> “inaugural year of physics data-taking with proton-proton … “

Should I take this to mean that I am not going to present any kind of analysis from Run 23 or is it that you want a clear distinction made between those analyses (calorimeter only and thus limited scope) and the analyses from Run 24 (trackers at the end - in theory data can serve the entire physics program ) ?

Super Pioneering High Energy Nuclear Interaction eXperiment (sPHENIX) is a high energy nuclear physics detector which is part of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) on Long Island, New York. sPHENIX is designed primarily to measure Quark-Gluon Plasma (QGP), produced in heavy-ion collisions at RHIC. QGP is a short-lived, hot, dense partonic medium which evolves similar to a liquid with near zero viscosity. The QGP is studied via the statistical properties of the bulk hadrons produced shortly after it expands and cools as well as internally generated probes produced from out-of-equilibrium high momentum transfer partonic scatterings at early times within itself. In particular, these hard scatterings produce collimated sprays of hadrons (jets) and high momentum heavy flavor hadrons which sPHENIX uses to probe the inner workings of the QGP. This talk will give an overview of the sPHENIX detector as well as present preliminary results from its inaugural year of physics data taking with \sqrt{s} = 200 GeV proton-proton collisions.

 Hi Charles and all,

Thanks for representing sPHENIX at the workshop.

I have just one request, which is to change “first two years of running” -> “inaugural year of physics data-taking with proton-proton … “ or similar. For a variety of reasons, we do not like to categorize Run-23 as a “real” year of data-taking — rather it is the year in which we started the commissioning process.

Hi Megan,

Thanks for the great advice. I took it all in with another removal. I got rid of "The proton-proton collisions serve as a reference point":

Hi Charles,

Thanks for the abstract. Here are some suggestions:

-remove the first instance of "detector" in the first sentence

-I would remove the second sentence. I worry it sounds like you are implying that we can't measure or would never be interested in p+A. If you want to state the collision energy and species I would add this information to the last sentence.

-"The Au-Au collisions produce Quark-Gluon Plasma (QGP)" to "sPHENIX is designed primarily to measure Quark-Gluon Plasma (QGP), produced in heavy-ion collisions. 

-Write out New York.

-"The proton-proton collisions serve as a reference point." to "Proton-proton collisions serve as a crucial reference for interpreting measurements in heavy ion collisions."

-Since our early results are actually bulk measurements, I think you should add something about bulk observables as well. 

-"as its primary physics program" to something like "to probe the inner workings of the QGP."

-"1st and 2nd years " to "first two years" 

Best, 

-Megan

Hi Charles,

I think sPHENIX stands for Super Pioneering High Energy Nuclear Interaction Experiment :)

I only know that because someone outside of sPHENIX asked and I had to look it up!

Happy NYE eve!

Hello All,

Below you will find my draft abstract and title for my plenary talk for the 11th workshop of the APS Topical Group on Hadronic Physics from March 14-16, 2025 in Anaheim, CA.

Apologies for sending this out on NYE eve - the abstract is due in 24 hours.
