摘要
We measured the branching fractions of the decays χcJ→Σ−Σ¯+ for the first time using the final states nn¯π+π−. The data sample exploited here is 448.1×106 ψ(3686) events collected with BESIII. We find B(χcJ→Σ−Σ¯+)=(51.3±2.4±4.1)×10−5,(5.7±1.4±0.6)×10−5, and (4.4±1.7±0.5)×10−5, for J=0, 1, 2, respectively, where the first uncertainties are statistical and the second systematic.Received 5 April 2020Accepted 20 April 2020DOI:https://doi.org/10.1103/PhysRevD.101.092002Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
