Abstract
We resolve the controversy in the high temperature behavior of the sphalero n rate in the abelian Higgs model in 1 + 1 dimensions. The T-2 behavior at intermediate lattice spacings is found to change into T-2/3 behavior in the continuum limit. The results are supported by analytic arguments that the classical approximation is good for this model.
