Abstract
We propose a radiative neutrino-mass model by introducing 3 generations of fermion pairs $E^{-(N+1)/2} E^{+(N+1)/2}$ and a couple of multi-charged 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, multi-charged leptons in the final state from the Drell-Yan production of $E^{-(N+1)/2} E^{+(N+1)/2}$. In general, the larger the $N$ the more charged leptons will appear in the final state.

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 Uð1ÞY hypercharge gauge coupling
We proposed a simple extension of the SM by introducing 3 generations of doubly charged fermion pairs E−−Eþþ and three multicharged bosonic fields kþþ; Φ3=2; Φ5=2, in which Φ are the SUð2Þ doublet fields and kþþ is a singlet field [6]
Summary
Nonzero neutrino mass is the most intriguing evidence for physics beyond the standard model (SM). A few of the earliest models are the Zee model [3], Babu model [4], and Ma model [5] It requires new particles running in the loop(s) of the neutrino-mass generating diagrams. These new particles can be light enough to be produced at colliders, offering immediate tests for the model. They could be relevant to explain other phenomena,. The model can explain the small neutrino masses and oscillations, muon anomalous magnetic moment, and is consistent with the lepton-flavor violations and the oblique parameters.
