Higgs alignment of visible and dark gauge groups

Abstract

We discuss a dark family of lepton-like particles with their own “private” gauge bosons वμ and धμ under a local SU’(2) × U’(1) symmetry. The product of dark and visible gauge groups SU’(2) × U’(1) × SUw(2) × UY(1) is broken dynamically to the diagonal (vector-like) subgroup SU(2) × U(1) through the coupling of two fields (math) to the Higgs field and the dark lepton-like particles. This defines a new Higgs portal, where the “dark leptons” can contribute to the dark matter and interact with Standard Model matter through Higgs exchange.
