Abstract

The relation between the specific shear viscosity η/s and the dimensionless jet quenching parameter q^/T3 in perturbative QCD is explored at next-to-leading order in the coupling constant. It is shown that the relation changes little, although both transport coefficients independently are subject to large modifications at the next-to-leading order level. This finding confirms that the relationship is robust.
