Search for hc ??+?-J /? via ? (3686) ??0?+?-J /?

Abstract

Using a data sample of 448.1×106 ?(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition hc??+?-J/? via ?(3686)??0hc. No signals of the transition are observed, and the upper limit on the product branching fraction B(?(3686)??0hc)B(hc??+?-J/?) at the 90% confidence level (C.L.) is determined to be 2.0×10-6. This is the most stringent upper limit to date. © 2018 authors.
