| contents | We propose an extension of the electroweak sector of the Standard Model in which the gauge group $SU(2)_L$ is promoted to $SU(2)_1 \times SU(2)_2$. This framework naturally includes a viable dark matter candidate and generates neutrino masses radiatively à la Scotogenic. Our scenario can be viewed as an ultraviolet extension of the Scotogenic mechanism, addressing some of its shortcomings. The resulting phenomenology may be probed through a range of experimental signatures, from precision electroweak measurements to searches for lepton flavor violation. |
