Electroweak Scale Neutrinos

We study a model of neutrino mass generation at the Electroweak scale (EW), where Lepton number is broken by the vacuum expectation value of a Standard Model singlet complex scalar field. No energy scales higher than the EW scale are introduced in the model and neutrinos can still get their tiny masses through the general seesaw mechanism. The neutrino Yukawa couplings need not be more suppressed than that of the electron. As part of our results we present the branching ratios of the possible Higgs decays, which should be detectable at near future colliders
