Book Description
We report on the observation of a narrow resonance at a mass of 2450 MeV/c2 in the final states .lambda. K−.pi./sup +/.pi./sup +/ and .sigma.°K−.pi./sup +/.pi./sup +/. The mass, width, lifetime, and decay modes support the interpretation of a hadronically produced charm-strange baryon, the .xi./sub c//sup +/. We present our preliminary measurements of the lifetime, and the .lambda., x/sub feynman, / and p/sub t/ dependence of the state.

Book Description
The lifetime of the [Lambda]0b baryon (consisting of u, d and b quarks) is the theoretically most interesting of all b-hadron lifetimes. The lifetime of [Lambda]0b probes our understanding of how baryons with one heavy quark are put together and how they decay. Experimentally however, measurements of the [Lambda]0b lifetime have either lacked precision or have been inconsistent with one another. This thesis describes the measurement of [Lambda]0b lifetime in proton-antiproton collisions with center of mass energy of 1.96 TeV at Fermilab's Tevatron collider. Using 1070 ± 60pb-1 of data collected by the Collider Detector at Fermilab (CDF), a clean sample of about 3,000 fully-reconstructed [Lambda]0b →[Lambda]c+[pi]- decays (with [Lambda]+c subsequently decaying via [Lambda]+c → p+ K- [pi]+) is used to extract the lifetime of the [Lambda]0b baryon, which is found to be c[tau]([Lambda]0b) = 422.8 ± 13.8(stat) ± 8.8(syst)[mu]m. This is the most precise measurement of its kind, and is even better than the current world average. It also settles the recent controversy regarding the apparent inconsistency between CDF's other measurement and the rest of the world.

Book 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} → [Delta]2K− establishes for the first time the importance of a W exchange mechanism in charmed baryon decay.
