Özet

Using a low-background sample of 2.6 x 10(5) J/psi -> omega eta(omega -> pi(+) pi(-) pi(0), eta -> gamma gamma) events, about 5 times larger statistics than previous experiments, we present a Dalitz plot analysis of the decay omega -> pi(+) pi(-) pi(0). It is found that the Dalitz plot distribution differs from the pure P-wave phase space with a statistical significance of 18.9 sigma. The parameters from the fit to data are in reasonable agreement with those without the cross-channel effect within the dispersive framework, which indicates that the cross-channel effect in omega -> pi(+) pi(-) pi(0) is not significant.
