Scalar–tensor baryogenesis: a scalar–tensor completion of gravitational baryogenesis
We propose Scalar–Tensor Baryogenesis (STB), in which the CP-violating bias needed for baryogenesis is sourced by the gravitational scalars that appear in scalar–tensor representations of modified gravity. Derivative couplings M*−d∇μf(ϕi)JB−Lμ act as an effective chemical potential μB−L∝f˙ in an FRW...
