Two Loop Finiteness of Higgs Mass and Potential in the Gauge-Higgs Unification

The zero mode of an extra-dimensional component of gauge potentials serves as a 4D Higgs field in the gauge-Higgs unification. We examine QED on M 4 × S 1 and determine the mass and potential of a 4D Higgs field (the A 5 component) at the two loop level with gauge invariant regularization. It is see...

Description
Summary:The zero mode of an extra-dimensional component of gauge potentials serves as a 4D Higgs field in the gauge-Higgs unification. We examine QED on M 4 × S 1 and determine the mass and potential of a 4D Higgs field (the A 5 component) at the two loop level with gauge invariant regularization. It is seen that the mass is free from divergences and independent of the renormalization scheme.
