Baryogenesis after Hyperextended Inflation
arXiv:hep-ph/0412020 · doi:10.1103/PhysRevD.72.043512
Abstract
We study a baryogenesis mechanism operating in the context of hyperextended inflation and making use of a coupling between the scalar field and a standard model global current, such as B or B-L. The method is efficient at temperatures at which these currents are not conserved due to some higher dimensional operator. The particle physics and cosmological phenomenology are discussed. We consider constraints stemming from nucleosynthesis and solar system experiments.
