Leptonic CP violation in flipped SU(5) GUT from $Z_{12-I}$ Orbifold Compactification

Abstract

We obtain a phenomenologically acceptable PMNS matrix in a flipped SU(5) model inspired by the compactification of heterotic string $E_8\times E_8^{\prime }$. To analyze the Jarlskog determinant efficiently, we include the simple Kim-Seo form for the Pontecorbo-Maki-Nakagawa-Sakata matrix. We also noted that $|{\delta }_{\mathrm{PMNS}}|\lesssim 64^{\mathrm{o}}$ for the normal hierarchy of neutrino masses with the PDG book parametrization.
