Abstract: (arXiv)

The decays of

J/\psi \to \omega K\bar{K}\pi

and

J/\psi \to \phi K\bar{K}\pi

are studied using

5.8 \times 10^{7}

J/\psi

events collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider (BEPC). The

K^{0}_{S}K^{\pm}\pi^{\mp}

and

K^{+}K^{-}\pi^{0}

systems, produced in

J/\psi \to \omega K\bar{K}\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\bar{K}\pi

system in

J/\psi \to \phi K\bar{K}\pi

. The branching fractions of

J/\psi \to \omega K^{0}_{S}K^{\pm}\pi^{\mp}

,

\phi K^{0}_{S}K^{\pm}\pi^{\mp}

,

\omega K^{*}\bar{K}+c.c.

, and

\phi K^{*}\bar{K}+c.c.

are obtained, and the

J/\psi \to \eta K^{0}_{S}K^{\pm}\pi^{\mp}

branching fraction is measured for the first time.
