Upgrades that are currently underway to maximize the physics output from Beam Energy Scan (BES) phase II will substantially enhance STAR's already excellent capabilities. These upgrades will enable STAR to continue its unique, ground-breaking mid-rapidity science program in the period following BES-II. The key physics opportunities envisioned address three broad areas of interest within the cold QCD community in the years following the BES-II. These programs will shed light on the dynamics of low and high x partons in cold nuclear matter (CNM) and how the fragmentation and hadronization of these partons is modified through interactions within the CNM and experiments to study the 2+1d spatial and momentum structure of protons and nuclei. These measurements will provide critical new insights into the QCD structure of nucleons and nuclei in the near term, as well as the high precision data that will be essential to enable rigorous universality tests when combined with future results from the Electron Ion Collider. In A+A collisions measurements with unprecedented precision using deep penetrating probes such as leptons and photons will enable us to probe the whole evolution of the collision. In addition, significantly improved hypertriton lifetime measurements may have important implications on astrophysics. The poster will highlight mid-rapidity physics program after the BES-II.
