Electroweak 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 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...
متن کاملModuli from Cosmic Strings
Moduli fields are generally present in superstring–inspired models. They are typically characterized by masses of the order of the supersymmetry breaking scale and by interactions of gravitational strength to ordinary matter. If stable, they can easily overclose the Universe. If unstable, strong limits on their abundance have to be imposed not to disrupt the successful prediction of nucleosynth...
متن کاملDF-strings from D3D̄3 as Cosmic Strings
We study Dirac-Born-Infeld type effective field theory of a complex tachyon and U(1)×U(1) gauge fields describing a D3D̄3 system. Classical solutions of straight global and local DFstrings with quantized vorticity are found and are classified into two types by the asymptotic behavior of the tachyon amplitude. For sufficiently large radial distances, one has linearlygrowing tachyon amplitude and ...
متن کاملCosmic sparks from superconducting strings.
We investigate cosmic sparks from cusps on superconducting cosmic strings in light of the recently discovered millisecond radio burst by Lorimer et al.. We find that the observed duration, fluence, spectrum, and event rate can be reasonably explained by grand unification scale superconducting cosmic strings that carry currents approximately 10{5} GeV. The superconducting string model predicts a...
