Chern-Simons term in the four-dimensional SU(2) Higgs model

Using Seibergs definition for the geometric charge in SU(2) lattice gauge theory, we have managed to apply it also to the Chern-Simons term. We checked the periodic structure and determined the Chern-Simons density on small lattices

L~4

and

L~3 \times 2,\, 4

with L=4,\, 6,\mbox{ and }8 near the critical region in the SU(2) Higgs model. The data indicate that tunneling is increased at high temperature.
