Low-scale baryogenesis from three-body decays Domínguez González, Francisco Racker, Juan 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. Baryogenesis from three-body decays (instead of two-body decays) has been proposed as a way for TeV scale baryogenesis. In this work we revisit this statement and show that, although three-body-decay models can provide interesting alternatives to address other kind of difficulties faced by low-scale baryogenesis, the generic problem due to the washouts proportional to the CP asymmetry persists. Therefore, as in two-body-decay models, the mass of the decaying particle cannot be below ∼10 TeV unless some mechanism to avoid these kinds of washouts is implemented. 2024-07-30T11:24:11Z 2024-07-30T11:24:11Z 2024-05-13 journal article Domínguez, F. & Racker, Phys.
