Theory Overview of Accessing Nuclear Structure in Heavy-Ion Collisions

In recent years, it has been discovered that the initial state of relativistic heavy-ion collisions is sensitive to nuclear structure. Head-on collisions of two nuclei produce the short-lived Quark Gluon Plasma that acts as a nearly perfect fluid such that imprints of the geometry of the initial collision region are preserved until the final state, which can be measured through multiparticle correlations. High-energy heavy-ions collisions have been used to extract information about deformation parameters, the size of nuclei, neutron skins, and alpha clustering. In this talk we will discuss the status of deformed nuclei that have already been ran at collider experiments: 238U, 129Xe, 96Ru, 96Zr, 16O, collaborations between high and low energy nuclear physicists, and potential future ions of interest.
