| 英文摘要 | The study of rho-omega mixing has mainly focused on vector meson decays with isospin I =1, namely the rho(omega) -> pi(+)pi(-) process. In this paper, we present a study of rho-omega mixing in rho(omega) ->pi(+)pi(-)pi(0) (I=0) using a flavor parameterization model for the J/psi -> VP process. By fitting a theoretical framework to PDG data, we obtain the SU(3)-breaking effect parameters sv = 0.03 +/- 0.12, Sp = 0.17 +/- 0.17 and the rho-omega mixing polarization operator II phi omega =(0.006 +/- 0.011) GeV2. New values are found for the branching ratios when the mixing effect is incorporated: Br(J/psi ->omega pi(0))= (3.64 +/- 0.37) x 10(-4), Br(J/psi -> omega n)= (1.48 +/- 0.17) x 10(-8), Br (J/psi -> omega n') = (1.55 +/- 0.56) x 10(-4), these are different from the corresponding PDG2012 values by 19%, 15% and 15%, respectively. |
