Query: Sphaleron Transition Rate in Presence of Dynamical Fermions   We investigate the effect of dynamical fermions on the sphaleron transition
rate at finite temperature for the Abelian Higgs model in one spatial
dimension. The fermion degrees of freedom are included through bosonization.
Using a numerical simulation, we find that massless fermions do not change the
rate within the measurement accuracy. Surprisingly, the exponential dependence
of the sphaleron energy on the Yukawa coupling is not borne out by the
transition rate, which shows a very weak dependence on the fermion mass.
