Lower bound for compactification scale from muon g−2 in the gauge-Higgs unification

We discuss a muon anomalous magnetic moment in a five dimensional SU(3) gauge-Higgs unification compactified on M4×S1/Z2 space-time including Z2-odd bulk mass for a fermion. We calculate one-loop corrections to the anomalous magnetic moment of muon and find a lower bound for the compactification scale to be around 5∼6TeV by comparing nonzero Kaluza-Klein mode contributions with the muon (g−2) experiment at BNL.
