Abstract

The resonant structure of the four pion final state in the decay τ→3ππ0ντ 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→3ππ0ντ decay has been performed; the spectral decomposition of the four pion system is dominated by the ωπ and a1π final states. The mass and width of the ρ′ resonance have been extracted from a fit to the τ→ωπντ spectral function. We have searched for second class currents in the decay τ→ωπντ using spin-parity analysis and established an upper limit on the non-vector current contribution.
