Abstract
We suggest that the massive right-handed neutrino in a specific version of left-right symmetric model can have a lifetime ≌ 1025 s and therefore, can not only act as a dark matter but also provide a source of anomalous positrons with energies higher than 10 GeV reported in cosmic ray experiments.

The idea that fermions acquire their masses via a universal seesaw mechanism can provide a plausible explanation for the mass hier- archy and an alternative way to account for the superlightness of neutrinos emerges.

From neutral-current constraints based on present experimental data, lower bounds of about 180 and 210 GeV are obtained for the second W and Z bosons of this model, respectively.

An extension of the left-right-symmetric model is presented by including extra singlet quarks and leptons, which leads to calculable W-L-R mixing and an ultralight Dirac mass for the neutrino.

In supersymmetric E/sub 6/ gauge models based on superstring theory, an exactly conserved multiplicative quantum number can be defined to separate all particles into two groups, making possible a truly massless Dirac neutrino whose right-handed component is effectively inert and a second W boson with a mass perhaps as low as 300 GeV in a model with unconventional particle assignments.
