The decay τ−→π−π+π−2π0ντ has been observed in e+e− annihilation using the CLEO II detector at the Cornell Electron Storage Ring. In a data sample collected at √s ∼10.6 GeV, 668±38 decay candidates have been identified by exclusively reconstructing two π0’s accompanying three charged particles, which...
