Description

In spring 2023, the sPHENIX detector at BNL’s Relativistic Heavy Ion Collider (RHIC) will begin measuring a suite of unique heavy flavor and quarkonia observables with unprecedented statistics and kinematic reach at the RHIC energies using combined electromagnetic and hadronic calorimeters and high precision tracking detectors. A Monolithic Active Pixel Sensor (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 to explore the parton energy loss mechanism, parton transport coefficients in Quark Gluon Plasma (QGP) and the hadronization process under different medium conditions. The physics program, its potential impact, and the recent detector development will be discussed in this talk.
