Simple description of neutrinos in image Original Research Article

We show that experimental results for the masses and mixing of the neutrinos can be understood naturally by a simple grand unification model of image coupled to image supergravity. No right-handed neutrinos are included. The left-handed neutrinos receive Majorana masses through the couplings with a Higgs boson of symmetric 15 representation. Introducing image representation is optional for describing the masses of down-type quarks and charged leptons.
