Subthreshold rho contribution in J/psi decay to omega pi pi and K(K)over-bar pi

We carry out a theoretical and Monte Carlo study on the J/psi decays into omega pi pi and KK pi though intermediate subthreshold rho meson by using SU(3)-symmetric Lagrangian approach. It is found that the subthreshold rho contribution is not negligible and may have significant influence on partial wave analysis of resonances in these channels, especially near the omega pi and KK thresholds.
