Scotogenic neutrino masses with gauged matter parity and gauge coupling unification

A bstract Building up on previous work we propose a Dark Matter (DM) model with gauged matter parity and dynamical gauge coupling unification, driven by the same physics responsible for scotogenic neutrino mass generation. Our construction is based on the extended gauge group SU(3) c ⊗ SU(3) L ⊗ U(1) X ⊗ U(1) N , whose spontaneous breaking leaves a residual conserved matter parity, M P , stabilizing the DM particle candidates of the model. The key role is played by Majorana SU(3) L -octet leptons, allowing the successful gauge coupling unification and a one-loop scotogenic neutrino mass generation. Theoretical consistency allows for a plethora of new particles at the ≲ $$ \mathcal{O} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>O</mml:mi> </mml:math> (10) TeV scale, hence accessible to future collider and low-energy experiments.
