Observation of the j/ψ and ψ(3686) decays into ης+σ¯-

HIGHLIGHTS

• who: M. Ablikim and collaborators from the Institute of High Energy Physics, Beijing, People`s Republic of China Beihang University have published the paper: Observation of the J/u03c8 and u03c8(3686) decays into u03b7u03a3+u03a3u00af-, in the Journal: (JOURNAL) of 16/Dec/2022
• what: The authors determine the branching fractions of these two decays to be B(J=u03c8 u2192 u03b7u03a3- u03a3u0304- (6.34 u00d7 10-5 and B(u03c8(3686) u2192 u03b7u03a3- u03a3u0304- (9.59 u00d7 10-6 where the first uncertainties are statistical and the second are systematic. The authors report the . . .
