We study the phenomenology of a Standard Model extension with two charged singlet scalars and three right-handed neutrinos at an electron-positron collider. In this model, the neutrino mass is generated radiatively at three-loop, the lightest right-handed neutrino is a good dark matter candidate, and the electroweak phase transition strongly first order as required for baryogenesis. We focus on the process e++e-→e-μ++Emiss, where the model contains new lepton flavor violating interactions that contribute to the missing energy. We investigate the feasibility of detecting this process at future e-e+ linear colliders at different centers of mass energies: ECM=250, 350, 500 GeV, and 1 TeV.
