We present a unified, gauge-invariant EFT analysis of low-scale electromagnetic leptogenesis sourced by CP-violating neutrino–gauge dipole interactions. We first match UV-complete models onto the dimension-six effective operator, and evaluate the decay widths, CP asymmetries, and the corresponding transport equations in the electroweak-broken phase. We then show that the suppression arising...
To investigate the finite mass effects in recently proposed monopole baryogenesis scenario, this study analyzes screening effect for the electric monopole charge, induced by CP-violating theta term, within a 't Hooft-Polyakov monopole background. Utilizing partial wave expansion and bosonized effective field theory for the massive charged fermions, we demonstrate that fermion finite masses...
