COSMOLOGICAL AND EXPERIMENTAL CONSTRAINTS ON THE TAU-NEUTRINO
Recent experimental results, together with a cosmological argument concerning the survival of primordially synthesized deuterium, exclude an unstable tau neutrino heavier than ≈ MeV. The cosmological bound on stable neutrinos then restricts it further to be lighter than ≈ 100 eV, in the absence of a...
