Abstract
We give arguments that in the 1 + 1-dimensional abelian Higgs model the cla ssical approximation can be good for the leading high-temperature behavior of real-time processes. The Chem-Simons diffusion rate ('sphaleron rate') i s studied numerically in this approximation. New results at high-temperatur e show a T-2/3 behavior of the rate at sufficiently small lattice spacing. (C) 1999 Elsevier Science B.V.
