SO(10)-GUT coherent baryogenesis Original Research Article

A model for GUT baryogenesis, coherent baryogenesis within the framework of supersymmetric image, is considered. In particular, we discuss the Barr–Raby model, where at the end of hybrid inflation charge asymmetries can be created through the time-dependent higgsino–gaugino mixing mass matrix. These asymmetries are processed to Standard Model matter through decays via nonrenormalizable image-violating operators. We find that a baryon asymmetry in accordance with observation can be generated. An appendix is devoted to provide useful formulas and concrete examples for calculations within image.
