Observation of the decay \(h_{c}\to3(π^{+}π^{-})π^{0}\)

By Besiii Collaboration and others
Based on \((2712.4\pm14.1)\times10^{6}\) \(\psi(3686)\) events collected with the BESIII detector, we study the decays \(h_{c}\to3(\pi^{+}\pi^{-})\pi^{0}\), \(h_{c}\to2(\pi^{+}\pi^{-})\omega\), \(h_{c}\to2(\pi^{+}\pi^{-})\pi^{0}\eta\), \(h_{c}\to2(\pi^{+}\pi^{-})\eta\), and \(h_{c}\to p\bar{p}\) via \(\psi(3686)\to\pi^{0}h_{c}\). The decay channel \(h_{c}\to3(\pi^{+}\pi^{-})\pi^{0}\) is observed for the first time, and its branching fraction is determined to be $\left( {9.28\pm 1.14 \pm 0.77} \right) \times {10^{ -...
