CKM matrix and FCNC suppression in SO(5)times U(1) times SU(3)SO(5)xU(1)xSU(3) gauge-Higgs unification
Original language description
The Cabibbo-Kobayashi-Maskawa (CKM) mixing matrix and flavor-changing neutral currents (FCNCs) in the quark sector are examined in the grand unified theory inspired SO(5)xU(1)xSU(3) gauge-Higgs unification in which the 4D Higgs boson is identified with the Aharonov-Bohm phase in the fifth dimension. Gauge invariant brane interactions play an important role for the flavor mixing in the charged-current weak interactions. The CKM matrix is reproduced except that the up quark mass needs to be larger than the observed one. FCNCs are naturally suppressed as a consequence of the gauge invariance, with a factor of order 10-6. It is also shown that induced flavor-changing Yukawa couplings are extremely small.
