Abstract

A lattice calculation is presented for the electrical conductivity of the QCD plasma with 2 + 1 dynamical flavours at nonzero temperature. We employ the conserved lattice current on anisotropic lattices using a tadpole-improved clover action and study the behaviour of the conductivity over a wide range of temperatures, both below and above the deconfining transition. The conductivity is extracted from a spectral-function analysis using the Maximal Entropy Method, and a discussion of its systematics is provided.
