Search for $h_c\to {\pi }^{+}{\pi }^{-}J/\psi$ via $\psi (3686)\to {\pi }^0{h}_c$

Abstract

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 $\mathcal{B}(\psi (3686)\to {\pi }^0{h}_c)\times \mathcal{B}(h_c\to {\pi }^{+}{\pi }^{-}J/\psi )$ and $\mathcal{B}(h_c\to {\pi }^{+}{\pi }^{-}J/\psi )$ at the 90$\%$ confidence level, which are determined to be $6.7\times 10^{-7}$ and $9.4\times 10^{-4}$, respectively.
