Radiative Interactions between New Non-Abelian Gauge Sector and the Standard Model

Abstract
We discuss one loop generation of the term connecting gauge fields from a local hidden and the standard model introducing an doublet fermion with non-zero hypercharge and a scalar field in adjoint representation. Then we obtain a kinetic mixing term between and gauge fields after the adjoint scalar field developing vacuum expectation value. We illustrate such a concrete scenario introducing a dark matter model in an ultraviolet (UV) completion with local symmetry where the scalar doublet is our dark matter candidate and its stability is guaranteed by remnant symmetry from . Relic density of dark matter is calculated focusing on the case in which dark matter annihilate into known particles via gauge interactions with radiatively induced kinetic mixing.
