On low-scale baryogenesis from three-body decays

Le résumé fourni par la source

Baryogenesis at the TeV scale from CP-violating decays of a massive particle requires some way to avoid the washouts from processes closely related to the existence of CP violation. It has been proposed that one way can be baryogenesis from three-body decays (instead of two-body decays). In this work we revisit this statement and show that, similarly to two-body-decay models, successful baryogenesis from three-body decays requires that the mass of the decaying particle be well above 10-100 TeV unless some other mechanism to avoid washouts is implemented.
