Revisiting electroweak symmetry breaking and the Higgs boson mass in gauge-Higgs unification

摘要

We propose a new model of five-dimensional S U ( 3 ) ? U ( 1 ) X gauge-Higgs unification with a successful electroweak symmetry breaking and a realistic Higgs boson mass. In our model, the representations of the fermions are very simple, the 3 , 3 ˉ and 15 ˉ representations of S U ( 3 ) gauge group. Employing the antiperiodic boundary conditions for 15 ˉ reduces massless exotic fermions and simplifies the brane-localized mass terms. We calculate the one-loop Higgs potential in detail and find that a realistic electroweak symmetry breaking and the observed Higgs mass are obtained.
