Abstract

We obtain a phenomenologically acceptable PMNS matrix in a flipped SU(5) model, possessing the Z _4R discrete symmetry, from the compactification of heterotic string E ₈ ×E ₈ ^′ . To analyze the Jarlskog determinant efficiently, we include the simple Kim-Seo form for the Pontecorbo-Maki-Nakagawa-Sakata matrix. We also noted that |δ _PMNS |≲63 ^o for the normal hierarchy of neutrino masses with the PDG book parametrization.
