Observation of a threshold enhancement in the $I ¨ ^{+} I ¨ ^{-}$ spectrum in $I ¨ (3686) \to I ¨ ^{+} I ¨ ^{-} J / I ¨ $ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +677

The BESIII experiment analyzed over 2.7 billion ψ(3686) decays and observed a clear resonance-like enhancement near the π⁺π⁻ mass threshold in ψ(3686)→π⁺π⁻J/ψ decays, measuring its…
