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}

π^{\mp}

and

K^{+}

K^{-}

π^{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}^{+}

and do not favor a

J^{P}

{= 0}^{-}

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}
