Description

The Dirac Scotogenic model provides an elegant mechanism for generating small Dirac neutrino masses at the one-loop level. A single abelian discrete ${\mathcal{Z}}_6$ symmetry simultaneously protects the ``Diracness'' of the neutrinos and the stability of the dark matter candidate. This symmetry originates as an unbroken subgroup of the so-called 445 $U(1{)}_{B-L}$ symmetry. Here we thoroughly explore the phenomenological implications of such a construction including analysis of electroweak vacuum stability, charged lepton flavor violation and the dark matter phenomenology. After taking all the constraints into account, we also show that the model allows for the possibility of novel low mass scalar as well as fermionic dark matter, a feature not shared by its canonical Majorana counterpart.
