Özet
Using (448.1 ± 2.9) × 106?(3686) events collected with the BESIII detector at the BEPCII collider, the decay ?(3686) ?? ?? ¯ + is observed for the first time with a branching fraction of (2.82 ± 0.04stat.± 0.08syst.) × 10?4, and the angular parameter ??? is measured to be 0.96 ± 0.09stat.± 0.03syst..
