Three-loop Neutrino Mass Model with Doubly Charged Particles from Iso-Doublets

Understand

We propose a new type of a three-loop induced neutrino mass model with dark matter candidates which are required for the neutrino mass generation.

• The smallness of neutrino masses can be naturally explained without introducing super heavy particles, namely, much heavier than a TeV scale and quite small couplings as compared to the gauge couplings.
• We find that as a bonus, the anomaly of the muon anomalous magnetic moment can simultaneously be explained by loop effects of new particles.
• In our model, there are doubly charged scalar bosons and leptons from isospin doublet fields which give characteristic collider signatures.
