Multiparticle azimuthal correlations in isobaric $^{96}$Ru+$^{96}$Ru and $^{96}$Zr+$^{96}$Zr collisions at $\sqrt{s_{NN}} =$ 200 GeV

Abstract: Correlations between event-by-event fluctuations in the amplitudes of flow harmonics offer a novel way to access initial state properties in heavy-ion collisions. We have extensively predicted correlations in different flow harmonics based on multiparticle cumulants in $^{96}$Ru+$^{96}$Ru and $^{96}$Zr+$^{96}$Zr collisions at $\sqrt{s_{NN}} =$ 200 GeV from a multiphase transport model. The state-of-the-art correlated nuclear distributions for the isobars were used to show the difference in nuclear deformations and neutron skin thickness, which have distinct characteristics seen in multiparticle azimuthal correlation. We also found a minimal effect of the shear viscosity effect on these multiparticle azimuthal correlations. Therefore, these studies could also serve as an additional tool for understanding the nature of the initial state fluctuations and nuclear structure, as well as input for possible in-depth dynamical studies for experimental measurement.
