Towards A Realistic Grand Gauge-Higgs Unification
Published 11 Jun 2007 in hep-ph | (0706.1397v2)
Abstract: We investigate a 5D SU(6) grand gauge-Higgs unification model compactified on an orbifold S1/Z_2. Ordinary quarks and leptons, together with right-handed neutrinos, are just accommodated into a minimal set of representations of the gauge group, without introducing any exotic states. The proton decay turns out to be forbidden at least at the tree level. We also find a correct electroweak symmetry breaking SU(2)L \times U(1)_Y \to U(1){em} is easily realized by introducing suitable number of adjoint fermions.
