Upper limit on the tau-neutrino mass.
A sample of lepton decays to 5± and 5±0 observed in the high-resolution spectrometer at the SLACe+e- storage ring PEP, has been used to place an upper limit on the mass of the tau neutrino of 84 MeV/c2 at the 95% confidence level. © 1986 The American Physical Society.
