Study of theKK¯πfinal state inJ/ψhadronic decays

The reactions J/ψ→ωKK¯π and J/ψ→φKK¯π have been studied in a sample of 5.8×${10}^6$ produced J/ψ decays. The systems $K^{\pm }$ $K_S^0$ ${\pi }^{\mp }$ and $K^{+}$ $K^{\mathrm{-}}$ ${\pi }^0$ produced in association with an ω have enhancements in the mass distribution near 1.44 GeV/$c^2$. The observed angular distributions are consistent with $J^P$ ${=1\mathrm{}}^{+}$ and do not favor a $J^P$ ${=0\mathrm{}}^{\mathrm{-}}$ assignment. No signal is seen at the nominal $f_1$(1285) mass. The reverse pattern is observed in the KK¯π system produced in association with a φ, which shows an enhancement near 1.280 GeV/$c^2$, and no evidence for structure at 1.4 GeV/$c^2$.
