Description
Understanding the many-body properties of ground-state light nuclear shape, is a key question to further study initial conditions and collectivity in high-energy small system collisions at RHIC and the LHC. In this talk, we interface insights from ab initio nuclear structure calculations of $^{16}$O geometry with simulations of high-energy $^{16}$O+$^{16}$O collisions. Bulk observables, such as the elliptic flow, mean transverse momentum fluctuations, and flow decorrelations, exhibit strong sensitivity to the nuclear model input, responding to realistic nucleon clustering and short-range repulsive correlations [1,2]. This approach provides a new avenue to probe these nuclear features experimentally, further constraining initial conditions in small-system collisions and enhancing connections to effective field theories of nuclei rooted in quantum chromodynamics.
