Leptogenesis with perturbations in type-II and type-III seesaw models
Abstract Density perturbations have recently been shown to lead to a novel effect in the freeze-out of heavy particles called “acoustically driven freeze-out.” This leads to an enhancement in the yield in standard leptogenesis. We extend this calculation to include $$2 \rightarrow 2$$ 2 → 2 washout...
