Generalized one-loop neutrino mass model with charged particles

We propose a radiative neutrino-mass model by introducing 3 generations of fermion pairs E-(N+1)/2E+(N+1)/2 and a couple of multicharged bosonic doublet fields Phi(N/2), Phi(N/2+1), where N = 1, 3, 5, 7, 9. We show that the models can satisfy the neutrino masses and oscillation data, and are consistent with lepton-flavor violations, the muon anomalous magnetic moment, the oblique parameters, and the beta function of the U(1)(Y) hypercharge gauge coupling. We also discuss the collider signals for various N, namely, multicharged leptons in the final state from the Drell-Yan production of E-(N+1)/2E+(N+1)/2. In general, the larger the N the more charged leptons will appear in the final state.
