Heavy meson decay in three-mesons and FSI

Abstract

The final state interaction (FSI) contribution to charged $D$ decay into $K\pi \pi$ is computed within a light-front framework, considering $S$-wave $K\pi$ interactions in $1/2$ and $3/2$ isospin states. The convergence of the rescattering series is checked computing terms up to the third perturbative order. The role of the resonances above $K_0^{\ast }(1430)$, and the contribution of the $K\pi$ $3/2$ isospin channel to charged three-body $D$ decays, are studied against the available phase-shift analysis.
