Simple description of neutrinos in SU(5)
arXiv:hep-ph/0310292 · doi:10.1016/j.nuclphysb.2004.09.004
Abstract
We show that experimental results for the masses and mixing of the neutrinos can be understood naturally by a simple grand unification model of SU(5) coupled to N=1 supergravity. No right-handed neutrinos are included. The left-handed neutrinos receive Majorana masses through the couplings with a Higgs boson of symmetric representation. Introducing representation is optional for describing the masses of down-type quarks and charged leptons.
