Probing the nuclear deformation with three-particle asymmetric cumulant in isobar collisions at RHIC

Mr Shujun Zhao (Peking University)


Isobar collisions at RHIC provide unique opportunities to study the geometry and fluctuations raised from the deformation of the colliding nuclei. Using iEBE-VISHNU hybrid model, we predict $ac_2\{3\}$ ratios between these two collision systems and demonstrate that the ratios of $ac_2\{3\}$, as well as the ratios of the involving flow harmonics and event-plane correlations, are sensitive to quadrupole and octupole deformations, which provides strong constrain on the shape differences between Ru and Zr.
