  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.
