Abstract

Results are presented from Fermilab E-400 on the production of charmed baryons and mesons at a mean energy of 640 GeV. We show evidence for the charm-strange baryon, Ξ_c⁺, and present our measurements of its mass, width, lifetime, cross section and relative branching fractions, and the A, ξ_f, p_t, and particle/antiparticle dependence of the state. We show evidence for both the Σ_c⁺⁺ and Σ_c⁰, and present measurements of three mass differences, Σ_c⁺⁺ - Σ_c⁰, Σ_c⁰ - Λ_c⁺, and Σ_c⁺⁺ - Λ_c⁺. Measurements of the A dependence and particle/antiparticle ratios for Σ_c production are also presented. We show preliminary results on the ratio of two decay modes of the D⁰, D⁰ → K⁺K^- and D⁰ → K₀K₀. The latter mode has not been previously observed.
