The effect of shear and bulk viscosities on elliptic flow
In this work, we examine the effect of shear and bulk viscosities on elliptic
flow by taking a realistic parameterization of the shear and bulk viscous
coefficients, and , and their respective relaxation times,
and . We argue that the behaviors close to ideal fluid
observed at RHIC energies may be related to non-trivial temperature dependence
of these transport coefficients.Comment: 6 pages, 4 figures, to appear in the proceedings of Strange Quark
