An upper limit for the τ neutrino mass from τ → 5π(π0)ντ decays

Physics Letters B, Volume 349, No. 4, Year 1995

From a sample of 152,000 τ decays collected by the ALEPH detector at LEP an upper limit of 24 MeV at 95% CL on the τ neutrino mass has been determined. The limit is obtained using a two dimensional likelihood fit of the visible energy and the invariant mass distribution of 25 τ → 5π(π0)ντ events. © 1995.
