Neutrino phenomenology in a little higgs model with gauge symmetry $SU(3)_c\otimes SU(4)_L\otimes U(1)_X$

Abstract: We carry out a search for possible mechanisms that explain the smallness of neutrino masses in the context of an anomaly-free Little Higgs model with electroweak gauge symmetry SU (4) L U (1) X. By the introduction of one neutral right-handed neutrino per generation, it is shown that the l...
