Systematic study of symmetric cumulants at $\sqrt{s_{NN}}$ = 200 GeV in Au+Au collision using transport approach

摘要

Measurement of 4-particle symmetric cumulants has been considered to be agood tool to study the correlations between amplitudes of different orders ofanisotropic flow harmonics in the heavy-ion collision. These new observablesnot yet been measured at RHIC. Using A Multi-Phase Transport model, a set ofpredictions for the centrality dependence of the normalized 4-particlesymmetric cumulants in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV has beengiven. In addition, the effects of shear viscosity and hadronic rescattering onthe magnitude of symmetric cumulants are discussed using AMPT model at$\sqrt{s_{NN}}$ = 200 GeV. It is shown that $sc(2,3)$ is found to be moresensitive to hadronic rescattering, whereas $sc(2,4)$ is more sensitive to theshear viscosity. Rapidity dependence of symmetric cumulants is also shown. Arelation between symmetric cumulant and event plane correlation is investigatedusing AMPT model.
