Abstract

An upper bound on the lifetime of a massive, neutral, weakly interacting lepton,

ν_{H}

, is derived from standard big-bang cosmology. Saturation of the bound and reasonable assumptions about the weak interaction of the

ν_{H}

then yield a prediction of approximately 10 MeV for its mass.
