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

We propose a new model of five-dimensional SU(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¯ and 15¯ representations of SU(3) gauge group. Employing the ant...

Description
Summary:We propose a new model of five-dimensional SU(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¯ and 15¯ representations of SU(3) gauge group. Employing the antiperiodic boundary conditions for 15¯ 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.
