Resumen:
In this work we study the influence of a temperature dependentshear viscosity-to-entropy ratio, eta/s, on hadronobservables as calculated within dissipative fluid dynamicswith a lattice QCD equation of state. In particular, we computethe Fourier moments v2 and v4 of the charged-hadronspectrum at RHIC energies in two different hydrodynamicformalisms, namely second-order theory and divergence typetheory. We compare the results obtained in bothframeworks and discuss their implications on the extractionof values of eta/s from data.
