Using a dataset of ( 27.12 ± 0.14 ) × 10 8 ψ ( 3686 ) events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of the decay ψ ( 3686 ) → Σ 0 …

Using $7.33\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collision data collected by the BESIII detector at c.m. energies between 4.128 GeV and 4.226 GeV, we observe for the first time the decay ${D}_{s}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\eta}$ with a statistical significance of $7.6\ensuremath{\sigma}$. The measured branching fraction of …
