Description
After briefly reviewing standard leptogenesis, we describe a new scenario, electromagnetic leptogenesis, that can fully explain the baryon-antibaryon asymmetry of the universe, just as standard leptogenesis can. Electromagnetic leptogenesis is driven by CP violation in the decays of heavy Majorana neutrinos to three-body final states that contain, in addition to the particles in standard leptogenesis, an electroweak gauge boson, which may be a photon, a Z, or a W.
