Abstract

Based on 106 million ψ(3686)\psi(3686) events collected with the BESIII detector at the BEPCII, the decay ψ(3686)→ωKKˉπ\psi(3686) \rightarrow \omega K \bar{K} \pi is studied. Enhancements around 1.44 GeV/c2c^{2} and the f1(1285)f_{1}(1285) are observed in the mass spectrum of KKˉπK \bar{K}\pi, and the corresponding branching fractions are measured, as well as the branching fractions of ψ(3686)→ωK∗+K−+c.c.\psi(3686) \rightarrow \omega K^{*+}K^{-}+c.c. and ψ(3686)→ωKˉ∗0K0+c.c.\psi(3686) \rightarrow \omega \bar{K}^{*0}K^{0}+c.c., all for the first time.
