Abstract

The resonant structure of the four pion final state in the decay τ→3ππ ν has been analyzed using 4.27 million τ τ pairs collected by the CLEO II experiment at the Cornell Electron Storage Ring. A partial wave analysis of the resonant structure of the ô-»3 τ→3ππ ν decay has been performed; the spectral decomposition of the four pion system is dominated by the ωπ and a π final states. The mass and width of the ρ′ resonance have been extracted from a fit to the τ→ωπν spectral function. We have searched for second class currents in the decay τ→ωπν using spin-parity analysis and established an upper limit on the non-vector current contribution. ©2000 The American Physical Society. 0 + - 0 τ τ 1 τ τ
