Electrweak Z-string And $\tanβ$
Abstract
Description
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. $\tanβ$. This ratio can be determined in terms of the couplings in the Higgs potential. Some remarks on the supersymmetric case are given. \noindent (Talk presented at SUSY '93, March 29-April 1st, Northeastern University, Boston, MA 02115, USA.)
