Abstract
I present a technique for measuring the broken phase sphaleron rate nonperturbatively. There are three parts to the calculation: determination of the probability distribution of Chern-Simons number NCS; measurement of <| d\NCS/dt |> at NCS=1/2, the mean rate of change of NCS at the barrier; and measurement of the ``dynamical prefactor,'' the fraction of barrier crossings which result in a permanent integer change in NCS.
