Study of c (3686) -> omega K(K)over-bar pi decays

Based on 106 million c d3686_ events collected with the BESIII detector at the BEPCII, the decay psi(3686) -> omega K (K) over bar pi is studied. Enhancements around 1.44 GeV/c(2) and the f1(1285) are observed in the mass spectrum of K (K) over bar pi, and the corresponding branching fraction ( upper limit) is measured, as well as the branching fractions of psi(3686) -> omega K*+K- + c.c. and psi(3686) -> omega(KK0)-K-*0 + c.c., all for the first time.
