Abstract

We suggest that the massive right-handed neutrino in a specific version of left-right symmetric model can have a lifetime {all equal to} 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.
