Abstract
We report on a detailed numerical calculation of the minimum mass of stable, massive neutrinos in order that the contribution of the primordial neutrinos not exceed allowable limits on the present mass density of the Universe. We find limits M≥1.3–4.2 GeV for Dirac neutrinos, and M≥4.9–13 GeV for Majorana neutrinos, in qualitative agreement with previous estimates.Keywords
