Search for h_c \to π^+π^-J/ψ via ψ(3686)\to π^0h_c

Using (2712.4 \pm 14.3) \times 10^6~\psi(3686) events collected with the BESIII detector operating at the BEPCII collider, we search for the hadronic transition h_c \to \pi^+\pi^-J/\psi via \psi(3686)\to \pi^0 h_c. No significant signal is observed. We set the most stringent upper limits to date on the branching fractions $\mathcal{B}(\psi(3686)\to \pi^0... Show more
