Abstract

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 × 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.
