Study of $ψ(3686) \rightarrow ωK \bar{K} π$ decays

Abstract

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