Description

Low-energy nuclear physics study shows that the shape of the nuclear could have a deformation from the spherical symmetry. At high-energy nuclear collisions, whether the picture is still the same is not clear. $^{129}$Xe nucleus has a quadrupole deformation measured by the low-energy nuclear physics experiments. And the Large hadron collider takes a $^{129}$Xe-$^{129}$Xe run at a per-nucleon center of mass energy of 5.44 TeV in 2017. There is an opportunity to probe the nuclear deformation at the LHC. The information on the nuclear structure is transferred to the final-state anisotropy of the system during the fluid expansion. The anisotropic flow observables, such as flow harmonics, nonlinear flow response, and symmetric cumulants could potentially be sensitive probes of the nuclear deformation.
In this study, with the simulation using the transport model (AMPT) with different overall quadrupole deformation and triaxial parameters, multiple anisotropic flow observables are calculated. The sensitivity of each observable to the deformation parameters will be presented on the poster.
