Abstract

We present comparisons to experimental data along with predictions of observables for $\text{U}+\text{U}$ and $\text{Au}+\text{Au}$ collisions at 193 and 200 GeV respectively, using a multistage theoretical and computational framework consisting of boost-invariant IP-Glasma initial state, music hydrodynamics, and a hadronic transport cascade generated by is3d and smash. Two different Woods-Saxon parametrizations were used for both systems [W. Ryssens et al., Phys. Rev. Lett. 130, 212302 (2023); H. De Vries et al., At. Data Nucl. Data Tables 36, 495 (1987)], allowing for comparisons within our model. Our results show great agreement with existing anisotropic flow measurements from the BNL Relativistic Heavy Ion Collider [L. Adamczyk et al., Phys. Rev. Lett. 115, 222301 (2015); J. Adam et al., Phys. Rev. Lett. 122, 172301 (2019)]. We provide predictions for differential flow observables as well as multiparticle correlations and transverse-momentum-flow correlations. When possible, we compare our predictions to results from $\text{Au}+\text{Au}$ collisions at 200 GeV to properly outline the effects of deformation in the initial state on final-state observables.
