A new model realizes the previously missing T4-3-i one-loop topology for Majorana neutrino mass, predicts one massless neutrino, and offers both fermionic and scalar dark matter candidates.

abstract
We discuss a new class of neutrino mass models generated in two loops, and explore specifically three new physics scenarios: (A) doubly charged scalar, (B) dark matter, and (C) leptoquark and diquark, which are verifiable at the 14 TeV LHC Run-II. We point out how the different Higgs insertions will distinguish our two-loop topology with others if the new particles in the loop are in the simplest representations of the SM gauge group.

A Novel One-loop Model for Majorana Neutrino Mass and Dark Matter
A new model realizes the previously missing T4-3-i one-loop topology for Majorana neutrino mass, predicts one massless neutrino, and offers both fermionic and scalar dark matter candidates.
