Scotogenic model from an extended electroweak symmetry
arXiv:2309.12091 · doi:10.1103/PhysRevD.110.035003
Abstract
We argue that the higher weak isospin manifestly unifies dark matter and normal matter in its isomultiplets for which dark matter carries a conserved dark charge while normal matter does not. The resultant gauge symmetry is given by , where the first factor is the color group, while the rest defines a theory of scotoelectroweak in which and determine electric charge and dark charge . This setup provides both appropriate scotogenic neutrino masses and dark matter stability as preserved by a residual dark parity . Interpretation of the dark charge is further discussed, given that is broken at very high energy scale.
