Two loop finiteness of Higgs mass and potential in the gauge-Higgs unification
Published 18 Sep 2007 in hep-ph | (0709.2844v1)
Abstract: 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 $M4 \times S1$ and determine the mass and potential of a 4D Higgs field (the $A_5$ component) at the two loop level with gauge invariant reguralization. It is seen that the mass is free from divergences and independent of the renormalization scheme.
