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

BESIII Collaboration

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