Abstract

Using a variation of Lueschers geometric charge definition for SU(2) lattice gauge theory, we have managed to give a geometric expression for it’s Chern-Simons term. From this definition we have checked the periodic structure. We determined the Chern-Simons density for latticesL4andL3×2, 4withL=4, 6, and 8near the critical region in the SU(2) Higgs model. The data indicate that tunneling is increased at high temperature.
