Abstract
The two-dimensional U(1)-gauged Higgs model is studied on an euclidean lattice of size , where the temperature is of the order of the sphaleron mass. The simulation parameters are taken from zero temperature results. By comparison with classical and semiclassical results I discuss, whether the sphaleron transition rate can be extracted from the behavior of the Chern-Simons number and from the formation of vortices in an euclidean simulation at high temperatures.
