Abstract

A limit on the mass of the tau neutrino m_ντ is derived from 4.5 × 10⁶ tau pairs produced in an integrated luminosity of 5.0 fb^-1 of e⁺e^- → γ * → τ⁺τ^- reactions at center of mass energies ≈ 10.6 GeV. The measurement technique involves a two-dimensional extended likelihood analysis, including the dependence of the end-point population on m_ντ, and allows for the first time an explicit background contribution. We use the the decays τ → 5πν_τ and τ → 3π2π⁰ν_τ to obtain an upper limit of 30 MeV/c² at 95% C.L.
