Light meson and baryon spectroscopy from charm decays in Fermilab E791
Abstract
Description
We present results from Fermilab experiment E791. We extracted the fractions of resonant components in the $Λ_c^+\to p K^- π^+$ decays, and found a significant polarization of the $Λ_c^+$ using a fully 5-dimensional resonant analysis. We also did resonant analyses of $D^+$ and $D^+_s$ decays into $π^+π^-π^+$. 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.
