英文摘要We study rho-omega interference by analyzing J/psi--> pi(+) pi(-) pidegrees pidegrees. PDG-2002 data on J/psi decays into PP and PV ( P denotes Pseudoscalar mesons; V, vector mesons) are used to fit a generic model which describes the J/psi decays. From the fits, we obtain anomalously large branching ratio Br (rhodegrees-->pi(+) pi(-) pi(degrees))approximate to 10(-3)-10(-2) A theoretical analysis for it is also provided, and the prediction is in good agreement with the anomalously large Br (rhodegrees-->pi(+) pi(-) pidegrees()). By the fit, we also get the eta-eta' mixing angle 0 - 19.68degrees +/- 1.49degrees and the constituent quark mass ratio m(u)/m(s) approximate to 0. 6 which are all reasonable.
