Description

This work investigates the consequence of the non-equilibrium phase space distribution on elliptic flow and particle spectra using a viscous hydrodynamic simulation. First, we show how various models of energy loss lead to different viscous corrections to spectra and make a connection between the shear viscosity coefficient and the transport parameter q-hat. The off-equilibrium distribution function is taken from leading order pQCD calculations which yields different corrections for quarks and gluons. Finally, we study a meson/baryon system with different viscous corrections due to the particles' different mean free paths. This leads to an alternative description of the experimentally observed quark number scaling.
