摘要：

The exact sphaleron solution in the bosonic sector of the electro-weak standard model is only known for weak mixing angle theta(W) = 0. To investigate the behaviour closer to the experimental value theta(W)exp almost-equal-to 30-degrees we construct a non-contractible loop in configuration space that is sensitive to theta(W). Our numerical results for the energy and the magnetic dipole moment, combined with previous perturbative results, indicate that the dependence on theta(W) is weak.
