Book excerpt: Various weak decays of the charmed baryon ..lambda../sub c/ are observed in the Mark II detector at the SLAC ee− storage ring SPEAR. Hadronic decays ..lambda../sub c/ ..-->.. pK−..pi..+ and ..lambda../sub c/+ ..-->.. pK/sub s/° and their conjugates are observed as peaks in invariant mass spectra at m(..lambda../sub c/) = (2286 +- 6) MeV/c2. An estimate of the charmed baryon production cross section, sigma(..lambda../sub c/) + sigma (anti ..lambda../sub c/) = (1.7 +- 0.4) nb, derived from Mark II measurements of the inclusive baryon cross sections R/sub p/ and R/sub ..lambda../ as functions of center-of-mass energy, is used to calculate branching ratios for these hadronic decays: BR (..lambda../sub c/+ ..-->.. p K− ..pi..+) = (2.0 +- 0.8)%; BR (..lambda../sub c//sup +/ ..-->.. p k/sub s/°)/BR (..lambda../sub c//sup +/ ..-->.. p K− ..pi../sup +/) = (36 +- 16)%. An attempt is also made to observe higher mass charmed baryons by reconstructing cascade decays ..sigma../sub c/ ..-->.. ..lambda../sub c/..pi ... Evidence for the observation of semileptonic decays of the charmed baryon is presented. Direct electrons are observed in events containing antiprotons, lambdas and antilambdas. The number of electrons per baryon event, after background subtraction and efficiency correction, is used, together with an estimate of the charmed baryon content of proton and lambda events, to calculate inclusive and semi-inclusive semileptonic branching ratios of the ..lambda../sub c.

Book excerpt: The authors present the first observation of the baryon decay?{sub b}° →?{sub c}?− followed by?{sub c}+ → pK−?+ in 106 pb−1 p{bar p} collisions at √s = 1.96 TeV in the CDF experiment. IN order to reduce systematic error, the measured rate for?{sub b}° decay is normalized to the kinematically similar meson decay {bar B}° → D+?− followed by D+ →?+K−?+. They report the ratio of production cross sections times the ratio of branching fractions for the momentum region integrated above p{sub T}> 6 GeV/c and pseudorapidity range.

Book excerpt: The authors present a precision measurement of the mass of the {Lambda}{sub c}{sup +} and studies of the production and decay of the {Omega}{sub c}{sup 0} and {Xi}{sub c}{sup 0} charm baryons using data collected by the BABAR experiment. To keep the systematic uncertainty as low as possible, the {Lambda}{sub c}{sup +} mass measurement is performed using the low Q-value decays, {Lambda}{sub c}{sup +} {yields} {Lambda}{sup 0} K{sub S}{sup 0}K{sup +} and {Lambda}{sub c}{sup +} {yields} {Sigma}{sup 0} K{sub S}{sup 0}K{sup +}. Several hadronic final states involving an {Omega}{sup -} and a {Xi}{sup -} hyperon are analyzed to reconstruct the {Xi}{sub c}{sup 0} and the {Omega}{sub c}{sup 0}.

Book excerpt: 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.
