摘要The decays of J/psi ->omega K (K) over bar pi and J/psi ->phi K (K) over bar pi are studied using 5.8x10(7) J/psi events collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider (BEPC). The K(S)(0)K(+/-)pi(-/+) and K(+)K(-)pi(0) systems, produced in J/psi ->omega K (K) over bar pi, have enhancements in the invariant mass distributions at around 1.44 GeV/c(2). However, there is no evidence for mass enhancements in the K (K) over bar pi system in J/psi ->phi K (K) over bar pi. The branching fractions of J/psi ->omega K(S)(0)K(+/-)pi(-/+), phi K(S)(0)K(+/-)pi(-/+), omega K*(K) over bar +c.c., and phi K*(K) over bar +c.c. are obtained, and the J/psi ->eta K(S)(0)K(+/-)pi(-/+) branching fraction is measured for the first time.
