Abstract

In a photoproduction experiment using a mean photon energy of 100 GeV we have observed 29±8 Λc(Λc) charmed-baryon and antibaryon decays in the pK−π+ (pK+π−) final state. Quasi two-body final states do not contribite significantly to this channel. The mass of the Λc was measured to be 2281.7±2.7±2.6 MeV/c2 and its lifetime 0.18±0.03±0.03 ps. The ratio of ΛcD production, measured in this experiment, is significantly greater than that predicted by photon-gluon fusion and using a Lund model to describe the hadronization. This excess cannot be completely accounted for in this model, even using a Λc branching fraction in pKπ as high as 5%.
