Resonant structure of 0 and decays Academic Article uri icon


  • The resonant structure of the four pion final state in the decay 30 has been analyzed using 4.27 million +- pairs collected by the CLEO II experiment at the Cornell Electron Storage Ring. A partial wave analysis of the resonant structure of the -3 30 decay has been performed; the spectral decomposition of the four pion system is dominated by the and a1 final states. The mass and width of the resonance have been extracted from a fit to the spectral function. We have searched for second class currents in the decay using spin-parity analysis and established an upper limit on the non-vector current contribution. 2000 The American Physical Society.
