We have investigated the build up of anisotropic flows within a parton cascade approach at fixed shear viscosity to entropy density η/s to study the generation of collective flows in ultrarelativistic heavy ion collisions. We present a study of the impact of a temperature dependent η/s(T) on the generation of the elliptic flow at both RHIC and LHC. Finally we show that the transport approach, thanks to its wide validity range, is able to describe naturally the rise-fall and saturation of the ν2(pT) observed at LHC.

Abstract

We have investigated the build up of anisotropic flows within a parton cascade approach at fixed shear viscosity to entropy density η/s to study the generation of collective flows in ultrarelativistic heavy ion collisions. We present a study of the impact of a temperature dependent η/s(T) on the generation of the elliptic flow at both RHIC and LHC. Finally we show that the transport approach, thanks to its wide validity range, is able to describe naturally the rise-fall and saturation of the ν2(pT) observed at LHC.
