Dissection of an SO(5) x U(1) Gauge-Higgs Unification Model

Abstract

We analyze models of electroweak symmetry breaking in warped 5-dimensional space with gauge bosons and fermions in the bulk. The Higgs boson is identified with the 5th component of a gauge field. We dynamically generate the Higgs potential using a competition between the top quark multiplet and another fermion multiplet to create a little hierarchy characterized by a small parameter s = v/f. Using a Green's function method, we compute the properties of the model systematically as a power series in s. We discuss the constraints on this model from the measured value of the Higgs mass, the masses of top quark partners, and precision electroweak observables.
