E687 Results on Charm Baryon Decays

Key Points

This research aims to measure the lifetimes and decay processes of various charm baryons produced in a photoproduction experiment.
Conducted measurements of Λ_c,Xi^+_c,Xi^0_c lifetimes.
Analyzed Cabibbo suppressed decay Λ_c^+-> pK^-K^+.
Provided preliminary results on charm baryon decays involving Σ^±.
Identified the lifetimes of Λ_c,Xi^+_c,Xi^0_c with specific measurements.

Presented preliminary data on Σ^± decay modes.

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.
