Description
In this work, we construct a two-loop radiative Majorana neutrino mass
model based on a dimension 7 gauge-invariant operator that violates the
lepton number by two units. The UV completion in this model includes a
scalar leptoquark doublet with hypercharge 1/6 and an additional vector-like
lepton doublet. It is shown that the neutrino mass matrix is proportional to
the masses of the heavy charged vector-like lepton and the top and bottom
quarks. In this model, we predict the rare charge lepton violation processes.
Integrating out the heavy charged and neutral components of vector-like
lepton induces a non-unitary PMNS mixing matrix.
