Physics Consequences of Extra-Dimensional Gauge-Higgs Unification

Abstract

In the dynamical gauge-Higgs unification of electroweak interactions, the 4D Higgs field is identified with the low energy mode of the extra-dimensional component of the gauge potentials. In the Randall-Sundrum warped spacetime, in particular, the Higgs boson mass is predicted in the range 120 GeV - 290 GeV. The universality of weak interactions is slightly broken by magnitudes of 10^{-8}, 10^{-6} and 10^{-2} for \mu-e, \tau-e and t-e, respectively.
