Název v původním jazyce

Beam energy dependence of the linear and mode-coupled flow harmonics in Au plus Au collisions

Popis výsledku v původním jazyce

The linear and mode-coupled contributions to higher-order anisotropic flow are presented for Au+Au collisions at root sNN = 27, 39, 54.4, and 200 GeV and compared to similar measurements for Pb+Pb collisions at the Large Hadron Collider (LHC). The coefficients and the flow harmonics' correlations, which characterize the linear and mode-coupled response to the lower-order anisotropies, indicate a beam energy dependence consistent with an influence from the specific shear viscosity (eta/s). In contrast, the dimensionless coefficients, mode-coupled response coefficients, and normalized symmetric cumulants are approximately beam-energy independent, consistent with a significant role from initial-state effects. These measurements could provide unique supplemental constraints to (i) distinguish between different initial-state models and (ii) delineate the temperature (T ) and baryon chemical potential (mu B) dependence of the specific shear viscosity eta s (T, mu B).
