Abstract

New results from the Fermilab photoproduction experiment E687 on charmed baryon decays are presented. The measurements of Λc, Xi^+c, Xi⁰c lifetimes and of the Cabibbo suppressed decay Λc^+-> pK^-K^+ are described. Preliminary results of charm baryon decays involving Σ^± with Σ^+->p\π⁰ or Σ^± ->n\π± are also given.
