Five-Dimensional Gauge-Higgs Unification: A Standard Model-Like Spectrum

Understand

We study the viability of five-dimensional gauge theories as candidates for the origin of the Higgs field and its mechanism for spontaneous symmetry breaking.

• Within the framework of lattice field theory, we consider the simplest model of an $SU(2)$ gauge theory.
• We construct this theory on a five-dimensional orbifold which explicitly breaks the gauge symmetry to $U(1)$ at the fixed points of the orbifold.
• Using anisotropic gauge couplings, we find that this theory exhibits three distinct phases which we label as confined, Higgs and hybrid.
