Abstract

The decays of a heavy lepton involving the hadronic vector current are calculated from electron-positron-annihilation data. The result,

Γ (τ^{-} \to ν_{τ} + {(2 n pions)}^{-}) = 1.69 Γ (τ^{-} \to ν_{τ} + e^{-} {\bar{ν}}_{e})

for

M_{τ} = 1.9

GeV and

m_{ν_{τ}} = 0

, and its implications are discussed.
