Kw. Edwards et al., Resonant structure of tau -> 3 pi pi(0)nu(tau) and tau ->omega pi nu(tau) decays - art. no. 072003, PHYS REV D, 6107(7), 2000, pp. 2003
The resonant structure of the four pion final state in the decay tau-->3 pi
pi(o)nu(tau) has been analyzed using 4.27 million tau(+)tau(-) pairs colle
cted by the CLEO II experiment at the Cornell Electron Storage Ring. A part
ial wave analysis of the resonant structure of the tau-->3 pi pi(o)nu(tau)
decay has been performed; the spectral decomposition of the four pion syste
m is dominated by the omega pi and a(1)pi final states. The mass and width
of the rho' resonance have been extracted from a fit to the tau-->omega pi
nu(tau), spectral function. We have searched for second class currents in t
he decay tau-->omega pi nu(tau) using spin-parity analysis and established
an upper limit on the non-rector current contribution.
