Abstract

Based on (2.712 ± 0.014) × 10⁹ ψ(3686) events collected with the BESIII detector, the decays (Formula presented) (J = 0, 1, 2) are observed for the first time with statistical significances exceeding 5σ. The measured branching fractions are (Formula presented), and (Formula presented), where the first uncertainties are statistical and the second systematic. In addition, no significant structures are observed in the (Formula presented), (Formula presented), and (Formula presented) mass spectra.
