Subthreshold rho contribution in J/psi decay to omega pion pion and Kaon anti-Kaon pion

Abstract

We carry out a theoretical and Monte Carlo study on the $J/\psi$ decays into $\omega \pi \pi$ and $K\bar{K}\pi$ through 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 $K\bar{K}$ thresholds.
