$D^{+}\to K^{-}{\text{p}}^{+}{\text{p}}^{+}$: the low-energy sector

Abstract

An effective $SU(3)\times SU(3)$ chiral lagrangian, which includes scalar resonances, is used to describe the process $D^{+}\text{rar}{K}^{-}{\text{p}}^{+}{\text{p}}^{+}$ at low-energies. Our main result is a set of five $S$-wave amplitudes, suited to be used in analyses of production data.
