Production and decay of the Lambda c charmed baryon from Fermilab E791

Description: Results are presented for the 500 GeV/c pion production asymmetry and polarization of the {Lambda}{sub c} ({bar {Lambda}}{sub c}) charmed baryon from Fermilab experiment E791. An analysis of the decay to the p{bar K}{pi} final state is described. Resonant sub-channel fractions and phases are given and possible resonant effects in the low mass p{bar K} system discussed. Significant decay to {Lambda}{sub c} {yields} {Delta}{sup 2}K{sup -} establishes for the first time the importance of a W exchange mechanism in charmed baryon decay.
