CKM matrix and FCNC suppression in SO(5)times U(1) times SU(3)SO(5)xU(1)xSU(3) gauge-Higgs unification

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 boso...
