dc.descriptionWe study S- and P-wave pion-pion and kaon-pion distributions for the three-body production processes $J/ψ\toωπ^{+}π^{-}$, $D^{+}\to K^{-}π^{+}π^{+}$, $D^{+}\to K^{+}π^{+}π^{-}$, and $D^{+}_{s}\to K^{+}π^{+}π^{-}$, by applying the Resonance-Spectrum Expansion to the two-body subamplitudes. The results are compared to the corresponding signals reported by the BES, E791 and FOCUS collaborations. We find that the studied S- and P-wave channels can largely account for the observed structures in the data up to 1 GeV.
