Supersymmetric Electroweak Cosmic Strings
We study the connection between N = 2 supersymmetry and a topological bound in a two-Higgs-doublet system with an SU(2)×U(1)Y ×U(1)Y ′ gauge group. We derive the Bogomol’nyi equations from supersymmetry considerations showing that they hold provided certain conditions on the coupling constants, which are a consequence of the huge symmetry of the theory, are satisfied. Their solutions, which can...
متن کاملElectroweak Baryogenesis with Cosmic Strings? Electroweak Baryogenesis with Cosmic Strings?
I report on a critical analysis of the scenario of electroweak baryoge-nesis mediated by nonsuperconducting cosmic strings. This mechanism relies upon electroweak symmetry restoration in a region around cosmic strings, where sphalerons would be unsuppressed. I discuss the various problems this scenario has to face, presenting a careful computation of the sphaleron rates inside the strings, of t...
متن کاملSupersymmetric Cosmic Strings
We study the formation of cosmic strings in the context of spontaneous symmetry breaking of gauge symmetry groups. We discuss the conditions for formation and stability of defects in nonsupersymmetric theories and also F-strings in the supersymmetry context. Finally, we discuss how cosmological observations can constrain supersymmetric grand unified theories.

متن کاملBaryogenesis from Cosmic Strings at the Electroweak Scale
We demonstrate the viability of baryogenesis from light scalar decays after the electroweak phase transition. A hidden fourth generation of quarks and leptons is used to introduce extra CP violations to the standard model. A simple extension of the standard model is constructed in which cosmic strings are formed at the electroweak phase transition. These strings decay into colored scalars which...
