Dear all,

Jorge's abstract was modified slightly to be a bit more specific. The current versions are:

sPHENIX Jet Performance Studies 

 

The sPHENIX detector at the Relativistic Heavy Ion Collider is designed to measure high transverse momentum probes of the quark-gluon plasma to study the small-scale structure of the QGP. Jets, the spray of particles created from a high momentum parton produced early in the collision, are an ideal probe as they experience the full evolution of the QGP. In order to understand the jet reconstruction in sPHENIX ahead of data taking, the performance is studied in simulation. Both effects from the detector as well as the performance and optimization of the subtraction of energy from the QGP underlying event are presented. In addition, the status of the detector assembly and testing are reported.

Calibrations of the sPHENIX Calorimeter System for Jet Reconstruction 

 

sPHENIX, which is scheduled to begin collecting data at the Relativistic Heavy Ion Collider in February 2023, is composed of tracking detectors and calorimeters. The calorimeters are designed to precisely measure the energy of jets which are sprays of particles resulting from an energetic quark or gluon produced early in the collision. Detailed studies of the modification to these jets in heavy ion collisions are excellent probes of the quark gluon plasma produced in such collisions. The sPHENIX calorimeters include an electromagnetic calorimeter, an inner and outer hadronic calorimeter located inside and outside the solenoid magnet respectively.

In preparation for data collection, initial calibrations have been determined and strategies for the calibrating the individual systems have been developed. This talk will focus on the later stages of the calibration process that ensures the combined jet energy is properly calibrated. In addition, this talk will report on hardware work related to these calibrations.

Dear all,

We have two GSU undergrads Damian and Jorge working at BNL with Virginia Bailey this summer. They will be doing a mix of hardware tasks as well as some calibration/jet studies. We would like for them to present this work at DNP and plan to submit the following abstracts. Please let us know if you have any feedback on the abstracts and if you are at BNL please introduce yourselves to them.

Best,

-Megan

In preparation for data collection, initial calibrations have been determined and strategies for calibrating the individual systems as well as the fully reconstructed jets have been developed. This talk will report on both hardware and software work related to these calibrations.
