Gauge-Higgs unification is the fascinating scenario solving the hierarchy problem without supersymmetry. In this scenario, the Standard Model (SM) Higgs doublet is identified with extra component of the gauge field in higher dimensions and its mass becomes finite and stable under quantum corrections due to the higher dimensional gauge symmetry. On the other hand, Yukawa coupling is provided by the gauge coupling, which seems to mean that the flavor mixing and CP violation do not arise at it stands. In this talk, we discuss that the flavor mixing is originated from simultaneously non-diagonalizable bulk and brane mass matrices. Then, this mechanism is applied to various flavor changing neutral current (FCNC) processes via Kaluza-Klein (KK) gauge boson exchange at tree level and constraints for compactification scale are obtained.

“…With these parameters fixed, wave functions of quarks and leptons are determined. In the present paper, we mostly ignore the flavor mixing in the quark and lepton gauge couplings [14,[82][83][84][85][86][87][88]. It has been shown that the Cabibbo-Kobayashi-Maskawa (CKM) mixing matrix can be incorporated in GHU with naturally suppressed FCNCs (flavor changing neutral currents) [14].…”

Fermion pair production at e − e þ linear collider experiments with polarized e − and e þ beams is examined in the GUT inspired SOð5Þ × Uð1Þ × SUð3Þ gauge-Higgs unification. There arises large parity violation in the couplings of leptons and quarks to Kaluza-Klein (KK) excited neutral vector bosons Z 0 s, which leads to distinctive polarization dependence in cross sections, forward-backward asymmetries, leftright asymmetries, and left-right forward-backward asymmetries in various processes. Those effects are detectable even for the KK mass scale up to about 15 TeV at future e − e þ linear collider experiments with energies 250 GeV to 1 TeV.

We discuss new-type grand unified theories based on grand unified groups broken to their special subgroups as well as their regular subgroups. In the framework, when we construct four-dimensional (4D) chiral gauge theories, i.e., the Standard Model (SM), 4D gauge anomaly cancellation restricts the minimal number of generations of the 4D SM Weyl fermions. We show that in a six-dimensional (6D) SU (16) gauge theory on M 4 × T 2 /Z 2 one generation of the SM fermions can be embedded into a 6D bulk Weyl fermion. For the model including three chiral generations of the SM fermions, the 6D and 4D gauge anomalies on the bulk and fixed points are canceled out without exotic 4D chiral fermions. * Electronic address: yamatsu@cc.kyoto-su.ac.jp
