Phys. Rev. D 43, 3599–3610 (1991)Inclusive production of the charmed baryon Λc+ from e+e- annihilations at √s=10.55 GeVReceived 27 August 1990; published in the issue dated 1 June 1991 We report results on inclusive production of the charmed baryon Λc+ from e+e- annihilations at √s=10.5 GeV. Measurements are presented of the inclusive cross section times branching fraction for the continuum production of Λc+ as observed in six different decay modes, and of a new, improved value of the Λc+ mass. The inclusive cross section times the branching fraction into pK-π+ is measured to be 10.0±1.5±1.5 pb summed over all xp. The branching fractions of Λc+ into pK̅ 0, pK̅ 0π+π-, Λπ+, Λπ+π-π+, and Ξ-K+π+ relative to that into pK-π+ are measured to be 0.44±0.07±0.05, 0.43±0.12±0.04, 0.18±0.03±0.03, 0.65±0.11±0.12, and 0.15±0.04±0.03, respectively. The Λc+ mass is measured to be 2284.7±0.6±0.7 MeV/c2. The measured momentum distributions for continuum production of Λc+ are compared to analytical fragmentation functions and to other measurements. © 1991 The American Physical Society URL:
