abstract = {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.},
