AbstraktAbstract
The effective potential for the Aharonov-Bohm phase θH in the fifth dimension in GUT inspired SO(5)×U(1)×SU(3) gauge-Higgs unification is evaluated to show that dynamical electroweak symmetry breaking takes place with θH≠0, the 4D Higgs boson mass 125GeV being generated at the quantum level. The cubic and quartic self-couplings (λ3,λ4) of the Higgs boson are found to satisfy universal relations, i.e. they are determined, to high accuracy, solely by θH, irrespective of values of other parameters in the model. For θH=0.1 (0.15), λ3 and λ4 are smaller than those in the standard model by 7.7% (8.1%) and 30% (32%), respectively.
