Abstract

In the S O ( 5 ) × U ( 1 ) × S U ( 3 ) gauge-Higgs unification in the Randall-Sundrum (RS) warped space, neutrino oscillations and the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix in the W couplings originate from Majorana mass terms on the ultraviolet brane in the RS space. Tiny neutrino masses are generated by an inverse seesaw mechanism. The PMNS matrix in the normal ordering with δ CP = π naturally arises consistently with the NuFit-6.0 analysis of neutrino oscillation data.
