Description
We examine the possibility of embedding a 17-keV neutrino in a left-right model with three generations of left- and right-handed neutrinos. In particular, we study scenarios where the 17-keV neutrino is a pseudo Dirac neutrino and its mass is generated radiatively. Two heavy right-handed neutrinos have their mass scale set by the SU(2)R-breaking scale, and the two light-neutrino masses are then determined by a seesaw mechanism. This scenario requires new Higgs bosons beyond those necessary in a minimal left-right model. The left-right symmetry leads to relations between the charged- and neutral-lepton mass matrices. We examine the constraints on the model from charged-lepton masses, leptonic flavor-changing neutral currents, neutrino data, cosmology, and astrophysics
