Testing Leptogenesis via CP asymmetries in Lepton-Number-Violating $W$ Decays at Colliders

Jean-François Fortin, Alessandro Granelli, David London +2

In principle, searches for CP asymmetries in rare $W$-boson decays can test low-scale leptogenesis in the GeV-scale type-I seesaw with three quasi-degenerate-in-mass heavy right-ha…
