Abstract

The resonant structure of the four pion final state in the decay (Formula presented) has been analyzed using 4.27 million (Formula presented) pairs collected by the CLEO II experiment at the Cornell Electron Storage Ring. A partial wave analysis of the resonant structure of the (Formula presented) decay has been performed; the spectral decomposition of the four pion system is dominated by the (Formula presented) and (Formula presented) final states. The mass and width of the (Formula presented) resonance have been extracted from a fit to the (Formula presented) spectral function. We have searched for second class currents in the decay (Formula presented) using spin-parity analysis and established an upper limit on the non-vector current contribution. © 2000 The American Physical Society.
