Abstract

Using (2.712±0.014)×109 ψ(3686) events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of ψ(3686)→3φ decay with a significance larger than 10σ. 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 φφ invariant mass spectra.
