Theta term instead of the Higgs field in Electroweak theory
arXiv:hep-lat/0110191
Abstract
We consider the electroweak theory without fundamental scalar field. The topological excitation of the SU(2)*U(1) theory (the monopole) plays the role of the Higgs field, it carries the SU(2)*U(1) topological charge due to the theta--term of the special type.
