Production and Decay of the Λ_c Charmed Baryon from Fermilab E791 Available to Purchase

Results are presented for the 500 GeV/c pion production asymmetry and polarization of the Λ_c $(Λc¯)$ charmed baryon from Fermilab experiment E791. An analysis of the decay to the pK̄π final state is described. Resonant sub‐channel fractions and phases are given and possible resonant effects in the low mass pK̄ system discussed. Significant decay to Λ_c → Δ⁺⁺K⁻ establishes for the first time the importance of a W exchange mechanism in charmed baryon decay.
