Evidence for $η_{c} (2 S) \to p p ˉ π^{+} π^{-} π^{0}$ and observation of $χ_{c J} \to p p ˉ π^{+} π^{-} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +771

Using $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected by the BESIII detector at the BEPCII collider, the $ψ (3686) \to γ p p ˉ π^{+} π^{-} π^{0}$ process is investigated. Evidence…
