Electrweak Z-string And β
Abstract
In the standard model with two Higgs doublets it is shown that the existence of the electroweak Z-string in general requires the same characteristic length for the two Higgs fields as well as a specific ratio of the two Higgs vacuum expectation values, i.e. β. This ratio can be determined in terms of the couplings in the Higgs potential. Some remarks on the supersymmetric case are given.
