Study of $\psi (3686)\to \omega K\bar{K}\pi$ decays

Abstract

Based on 106 million $\psi (3686)$ events collected with the BESIII detector at the BEPCII, the decay $\psi (3686)\to \omega K\bar{K}\pi$ 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 $\psi (3686)\to \omega K^{\ast +}{K}^{-}+c.c.$ and $\psi (3686)\to \omega {\bar{K}}^{\ast 0}{K}^0+c.c.$, all for the first time.
