Heavy-Ion Collisions as Probes of Nuclear Structure (2405.17526v2)

Published 27 May 2024 in nucl-th

Abstract: In this work, we perform a model-to-data comparison for U+U and Au+Au collisions performed at RHIC at $\sqrt{s_{\rm NN}}$ = $193$ GeV and $200$ GeV, using a multistage framework. Model calculations for various configurations of ${238}$U and ${197}$Au are used to compare with measurements of $\rho(v_n{2}2,\left\langle p_T \right\rangle)$, the elliptic-flow-momentum correlator, for the first time. It is found that momentum-flow correlations measured in high-energy nuclear collisions, combined with the flow harmonics themselves, are excellent probes of nuclear deformation and of nuclear structure in general.
