Description
The STAR experiment at the Relativistic Heavy-Ion Collider has recently released findings regarding exclusive coherent and incoherent photoproduction of $J/\psi$ mesons in Au+Au ultra-peripheral collisions (UPCs). In this talk, I will delve into the preliminary findings and examine how they influence our understanding of nuclear parton density within heavy nuclei and the event-by-event density fluctuation. The data will be rigorously assessed through quantitative comparisons with various models. Furthermore, I will outline prospective avenues for future research opportunities in UPCs.
