Description

In 2023, the sPHENIX detector at BNL’s Relativistic Heavy Ion Collider (RHIC) will begin measuring a suite of unique jet and heavy flavor observables with unprecedented statistics and kinematic reach at the RHIC energies using combined EM and hadronic calorimeters and high precision tracking.
The experiment incorporates full azimuth vertexing, tracking, and a complete set of electromagnetic and hadronic calorimetry for electron identification enabling detailed studies of the three Upsilon States, Y(1S), Y(2S) and Y(3S). Because of the different binding energies, bottomonium mesons are particularly useful probes to understand the thermal properties of quark-gluon plasma. sPHENIX will provide high statistics measurements of the separated three Upsilon states over a broad momentum range for the first time at RHIC. A MAPS-based vertex detector upgrade to sPHENIX, the MVTX, will provide a precise determination of the impact parameter of tracks relative to the primary vertex in high multiplicity heavy-ion collisions and polarized proton-proton/proton-nuclei collisions. It will enable precision measurements of open heavy-flavor observables, covering an unexplored kinematic region at RHIC. This talk will describe the current projections for the sPHENIX open and closed heavy flavor measurements in hot and cold nuclear matter and discuss their potential scientific impact.
