SecondOrder Hydrodynamics in NexttoLeadingOrder QCD
Abstract
We compute the hydrodynamic relaxation times τ_{π} and τ_{j} for hot QCD at nexttoleading order in the coupling with kinetic theory. We show that certain dimensionless ratios of secondorder to firstorder transport coefficients obey bounds which apply whenever a kinetic theory description is possible; the computed values lie somewhat above these bounds. Strongly coupled theories with holographic duals strongly violate these bounds, highlighting their distance from a quasiparticle description.
