Quark-Lepton Complementarity Model Based Predictions for θ~(PMNS)_(23) with Neutrino Mass Hierarchy

摘要

57.1 Introduction The recent results from various neutrino oscillation experiments [1] in past several years have provided us a very strong sign of neutrinos being massive, the mixing of lepton flavours and their oscillations. After the successful investigation of θPMNS13 [2], there are certain issues that are not settled yet, out of which one is the problem of mass hierarchy in the neutrino mass spectrum and another is the quadrant of angle θPMNS23 _(are) the challenges that are to be settled.
