A variation on the abelian Higgs model, with SU(2)global x U(1)local symmetry broken to U(1)global, was recently shown by Vachaspati and Achucarro to admit stable, finite-energy cosmic string solutions, even though the manifold of minima of the [...]![]()

It is shown that any sigma model coupled to gravity with a target space having closed geodesics admits singular cosmic string solutions with event horizons. We also prove that if one makes the general assumption of boost symmetric sources, non-s[...]
