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

TL;DR

This study analyzes the decay of $ ext{psi}(3686)$ into $ ext{omega} ext{K} ar{ ext{K}} ext{pi}$ using 106 million events, observing mass spectrum enhancements and measuring branching fractions for the first time.

Contribution

First measurement of branching fractions for $ ext{psi}(3686)$ decays into $ ext{omega} ext{K} ar{ ext{K}} ext{pi}$ and related channels, with observation of spectrum enhancements.

Findings

Enhancements around 1.44 GeV/$c^{2}$ and $f_{1}(1285)$ observed in $K ar{K} ext{pi}$ spectrum.

Branching fractions for $ ext{psi}(3686) ightarrow ext{omega} ext{K}^{*+} ext{K}^{-}+c.c.$ and $ ext{psi}(3686) ightarrow ext{omega} ar{ ext{K}}^{*0} ext{K}^{0}+c.c.$ measured for the first time.

Abstract

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.
