Description
The exact Sphaleron solution in the bosonic sector of the electro-weak standard model is only known for weak mixing angle θW=0. To investigate the behaviour closer to the experimental value θWexp approx 30 deg a non-contractible loop in configuration space which is sensitive to θW is constructed. The numerical results for the energy and the magnetic dipole moment indicate that the dependence on θW is rather weak. (author). 8 refs.; 4 figs.; 1 tab
