dc.description.abstractUsing (2.712±0.014)×109 ?(3686) events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of ?(3686)?3? decay with a significance larger than 10?. The branching fraction of this decay is determined to be (1.46±0.05±0.17)×10-5, where the first uncertainty is statistical and the second is systematic. No significant structure is observed in the ?? invariant mass spectra. © 2024 authors. Published by the American Physical Society.
