Collective Flows in a Transport Approach

We introduce a transport approach at fixed shear viscosity to entropy ratio η/s to study the generation of collective flows in ultra-relativistic heavy-ion collisions. Transport theory supplies a covariant approach valid also at large η/s and at intermediate transverse momentum pT, where deviations...

Description
Summary:We introduce a transport approach at fixed shear viscosity to entropy ratio η/s to study the generation of collective flows in ultra-relativistic heavy-ion collisions. Transport theory supplies a covariant approach valid also at large η/s and at intermediate transverse momentum pT, where deviations from equilibrium is no longer negligible. Such an approach shows that at RHIC energies a temperature dependent η/s enhances significantly the v4/v22 respect to the case of constant η/s. Furthermore if NJL chiral dynamics is self-consistently implemented we show that it does not modify the relation between v2 and η/s.
