Metastable strings and dumbbells in supersymmetric hybrid inflation

Abstract We study symmetry breaking and topological defects in a supersymmetric model with gauge group U(2), which can be identified with the right-handed part SU(2) R × U(1) B−L of an extended electroweak symmetry of the Standard Model. The model has two phases of hybrid inflation terminated by tac...
