Abstract
We propose the simplest TeV-scale scotogenic extension of the original 3-3-1 theory, where dark matter stability is linked to the Dirac nature of neutrinos, which results from an unbroken $B-L$ gauge symmetry. The new gauge bosons get masses through the interplay of spontaneous symmetry breaking \`a la Higgs and the Stueckelberg mechanism.

Despite its amazing phenomenological success, almost no one thinks of the standard model as the final theory, so many are its drawbacks

We build up upon a minimal gauge extension of the original Singer-Valle-Schechter (SVS) 3-3-1 model [1]. This was the first electroweak extension of the standard model in which the existence of three families of quarks and leptons is closely related to anomaly cancellation
Summary
Despite its amazing phenomenological success, almost no one thinks of the standard model as the final theory, so many are its drawbacks. We build up upon a minimal gauge extension of the original Singer-Valle-Schechter (SVS) 3-3-1 model [1] This was the first electroweak extension of the standard model in which the existence of three families of quarks and leptons is closely related to anomaly cancellation. An alternative proposal to link Dirac neutrino masses and dark matter stability is through a fully conserved global B − L symmetry. This is achieved within a richer framework that provides a dynamical realization of the proposal that dark matter stability and Diracness are closely interrelated, and touches other standard model shortcomings such as the number of families and the strong CP problem.
