Minimal electroweak baryogenesis via domain walls by Jacopo Azzola, Oleksii Matsedonskyi, Andreas Weiler

“…Abstract The Standard Model extended by a real scalar singlet S with an approximate ℤ 2 symmetry offers a minimal framework for realizing electroweak baryogenesis (EWBG) during a first-order electroweak phase transition. …”

Electromagnetic leptogenesis with light-heavy sterile neutrinos by Debasish Borah, Arnab Dasgupta

“…The asymmetry in left handed leptons is then converted to baryon asymmetry via electroweak sphalerons. The lepton number violation by heavy RHN also induces a one-loop Majorana mass of νR rendering the light neutrinos to be Majorana fermions. …”
