Lepton-mediated electroweak baryogenesis, gravitational waves and the 4τ final state at the collider
Abstract An electroweak baryogenesis (EWBG) mechanism mediated by τ lepton transport is proposed. We extend the Standard Model with a real singlet scalar S to trigger the strong first-order electroweak phase transition (SFOEWPT), and with a set of leptophilic dimension-5 operators to provide suffici...
