dc.description.abstractBased on (2712.4±14.1)×106 ?(3686) events collected with the BESIII detector, we study the decays hc?3(?+?-)?0, hc?2(?+?-)?, hc?2(?+?-)?0?, hc?2(?+?-)?, and hc?pp¯ via ?(3686)??0hc. The decay channel hc?3(?+?-)?0 is observed for the first time, and its branching fraction is determined to be (9.28±1.14±0.77)×10-3, where the first uncertainty is statistical and the second is systematic. In addition, first evidence is found for the modes hc?2(?+?-)?0? and hc?2(?+?-)? with significances of 4.8? and 4.7?, and their branching fractions are determined to be (7.55±1.51±0.77)×10-3 and (4.00±0.86±0.35)×10-3, respectively. No significant signals of hc?2(?+?-)? and hc?pp¯ are observed, and the upper limits of the branching fractions of these decays are determined to be <6.19×10-4 and <4.40×10-5 at the 90% confidence level, respectively. © 2024 authors.
