Query: High Temperature Behavior of the Chern-Simons Diffusion Rate in the 1+1
  D Abelian Higgs Model   We give arguments that in the 1+1 dimensional abelian Higgs model the
classical approximation can be good for the leading high temperature behavior
of real time processes. The Chern-Simons diffusion rate (`sphaleron rate') is
studied numerically in this approximation. New results at high temperature show
a $T^{2/3}$ behavior of the rate at sufficiently small lattice spacing.
