Description
Square root metric geometry has extra U(4')×U(4)-bundle, then a Pati-Salam model in curved space-time and Einstein-Cartan gravity theory can be constructed based on self-parallel transport principle. A fermions representation scheme is suggested, three families quarks and leptons find the place in the fermions representation scheme; flavor mixing matrices, CKM (Cabibbo-Kobayashi-Maskawa) and PMNS (Pontecorvo-Maki-Nakagawa-Sakata) matrices, are constructed. The beyond-SM (Standard Model) semi-leptonic processes transported by X bosons and beyond-SM FCNCs (flavor changing neutral currents) transported by Y bosons are pointed out.
