Abstract
Using a data sample of 448.1 × 106 ψ(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition hc → π + π−J = ψ via ψ(3686) → π0hc. No signals of the transition are observed, and the upper limit on the product branching fraction B(ψ(3686) → π0hc)B(hc → π + π −J =ψ) at the 90% confidence level (C.L.) is determined to be 2.0 × 10−6. This is the most stringent upper limit to date.
