Abstract: (APS)
The mass of the τ lepton has been measured at the Beijing Electron-Positron Collider using the Beijing Spectrometer. A search near threshold for e+e−→τ+τ− was performed. Candidate events were identified by requiring that one τ decay via τ→eνν¯, and the other via τ→μνν¯. The mass value, obtained from a fit to the energy dependence of the τ+τ− cross section, is mτ=1776.9−0.5+0.4±0.2 MeV.- electron positron: colliding beams
