A bstractWe propose a model which unifies the Left-Right symmetry with the SU(3)L gauge group, called flipped trinification, and based on the SU(3)C ⊗ SU(3)L ⊗ SU(3)R ⊗ U(1)X gauge group. The model inherits the interesting features of both symmetries while elegantly explaining the origin of the matter parity, WP = (−1)3(B−L)+2s, and dark matter stability. We develop the details of the spontaneous symmetry breaking mechanism in the model, determining the relevant mass eigenstates, and showing how neutrino masses are easily generated via the seesaw mechanism. Moreover, we introduce viable dark matter candidates, encompassing a fermion, scalar and possibly vector fields, leading to a potentially novel dark matter phenomenology.
