Light meson and baryon spectroscopy from charm decays in Fermilab E791

We present results from Fermilab experiment E791. We extracted the fractions of resonant components in the $\Lambda_c^+\to p K^- \pi^+$ decays, and found a significant polarization of the $\Lambda_c^+$ using a fully 5-dimensional resonant analysis. We also did resonant analyses of $D^+$ and $D^+_s$ decays into $\pi^+\pi^-\pi^+$. We observed an insignificant asymmetry in the Breit Wigner describing the $f_0(980)$ and found good evidence for a light and broad scalar resonance in the $D^+$ decays.
