Abstract

A variation on the abelian Higgs model, with global SU(2) x local U(1) symmetry broken to global U(1) was recently shown by Vachaspati and Achucarro to admit stable, finite energy cosmic string solutions even though the manifold of minima of the potential energy does not have non-contractible loops. Here the most general solutions, both in the single and multi-vortex cases, are described in the Bogomol'nyi limit. The gravitational field of the vortices considered as cosmic strings is obtained and monopole-like solutions surrounded by an event horizon are found.
