sPHENIX is a new detector at RHIC.

Hello Virginia,

Thank you for putting together such a nice abstract. I have made minor tweaks to the abstract wording below for your consideration, after which you are good to submit.

The sPHENIX detector at the Relativistic Heavy Ion Collider is designed to measure high momentum probes of the quark-gluon plasma such as jets. Jet measurements in heavy-ion collisions require subtraction of the large underlying event consisting of low momentum particles produced from the QGP medium. While subtraction techniques can remove the average size of the background, localized fluctuations can result in an over- or under-subtraction of the underlying event. This effect leads to an increase in the jet energy resolution, which can be understood through the size of the underlying event fluctuations. This poster presents a study of the expected jet energy resolution from both detector effects and underlying event fluctuations using simulations of the sPHENIX detector.

Best,

Tim

Dear all,

I would like to submit the following poster abstract to Quark Matter discussing my ongoing work in the jet structure group looking at the expected jet energy resolution and underlying event fluctuations in heavy ion collisions. Please let me know if there are any comments or suggestions on the abstract.

Best,

Title: Expected jet energy resolution and underlying event fluctuations in the sPHENIX detector

Abstract:

The sPHENIX detector at the Relativistic Heavy Ion Collider is designed to measure high momentum probes of the quark-gluon plasma such as jets. Jet measurements in heavy-ion collisions require subtraction of the large underlying event of low momentum particles produced from the QGP medium. While subtraction techniques can remove the average size of the background, local fluctuations can lead to an over- or under-subtraction of the underlying event. This effect leads to an increased jet energy resolution, which can be understood through the size of the underlying event fluctuations. This poster presents a study of the expected jet energy resolution from both detector effects and underlying event fluctuations using simulations of the sPHENIX detector.
