Temperature dependence of $\eta /s$ of strongly interacting matter: effects of the equation of state and the parametric form of $(\eta /s)(T)$

Jussi Auvinen, Kari J. Eskola, Pasi Huovinen +3

We investigate the temperature dependence of the shear viscosity to entropy density ratio $\eta /s$ using a piecewise linear parametrization. To determine the optimal values of the par…
