Toward a more complete description of hybrid leptogenesis

The hybrid leptogenesis framework combining the type-I and type-II seesaw mechanisms for neutrino mass necessarily include scattering topologies involving both the scalar triplet and the right-handed neutrino. We demonstrate that a systematic inclusion of these mixed scatterings can significantly al...

description The hybrid leptogenesis framework combining the type-I and type-II seesaw mechanisms for neutrino mass necessarily include scattering topologies involving both the scalar triplet and the right-handed neutrino. We demonstrate that a systematic inclusion of these mixed scatterings can significantly alter the evolution of the number densities exhibiting, up to a factor ten, deviation in the predicted asymmetry as demonstrated by our benchmark scenarios. We provide quantitative constraints on the degeneracy of the seesaw scales where the complete analysis becomes numerically significant, limiting the validity of leptogenesis being dominated by the lightest seesaw species only.
