Book Description
We have measured production of[pi][sup[+-]], [Kappa][sup[+-]], [ital p]/[ital[bar p]], [Kappa][sup 0] and[Lambda][sup 0]/[bar[Lambda]][sup 0] as a function of momentum in inclusive hadronic[ital Z][sup 0] decay events and separately in events containing primary light-([ital uds]) and[ital b]-quarks. The SLD Cherenkov Ring Imaging Detector was used to identify charged pions, kaons, and protons over most of the available momentum range 0.8[lt][ital p][lt]33 GeV/c. The neutral[Kappa][sup 0][sub s] and[Lambda][sup 0] were reconstructed using the[pi][sup+][pi][sup -] and[ital p][pi][sup -] decay modes, respectively. We present the first comparisons of momentum of charged tracks measured in the SLD Vertex Detector. Substantial differences are observed, consistent with the kinematics of[ital B]-hadron production in Z[sup 0] decays and the properties of[ital B]-hadron decays as measured at lower energies.

Book Description
We present a preliminary measurement of the inclusive production rates of K[sub s], A and X hadrons produced in e[sup +]e[sup [minus]] annihilation at the Z[sup 0] pole. The analysis is based upon approximately 50K Z[sup 0] decays collected in the SLD experiment at SLAC in 1993. The observed rates of (K[sub s]) = 1.02 [plus-minus] 0.02 [plus-minus] 0.09 and ([Lambda]) + ([bar [Lambda]]) = 0.38 [plus-minus] 0.01 [plus-minus] 0.04 are consistent with previous measurements. Our differential cross section peak-position results are shown to be consistent with QCD predictions based on the modified leading logarithm approximation and local parton-hadron duality.

Book Description
Production rates and momentum distributions have been measured for[pi][sup[+-]], K[sup[+-]], p, K[sup 0][sub s], [Lambda][sup 0], K[sup*0] and[phi] in 150,000 hadronic Z[sup 0] decays recorded by the SLD detector at the SLD collider at SLAC. The analysis uses the SLD Cerenkov Ring Imaging Detector (CRID) for clean and efficient identification of charged tracks and significant background reduction. In addition, K[sup*0] production has been studied in quark and anti-quark jet samples, which were identified by their electroweak forward backward asymmetries using the SLD high electron beam polarization. A difference between the two samples is observed in the K[sup*0] rate at high momentum, consistent with leading particle and strangeness suppression hypotheses.

Book Description
A Dalitz plot analysis of the D[sup 0] hadronic decays D[sup 0][yields] K[sup 0]K[sup -][pi][sup+], D[sup 0][yields][bar K][sup 0] K[sup+][pi][sup -] and D[sup 0][yields][bar K][sup 0] K[sup+] K[sup -] is presented. This analysis is based on a data sample of 22 fb[sup -1] collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC running on or near the[Upsilon](4S) resonance. The events are selected from continuum e[sup+]e[sup -] annihilations using the decay D*[sup+][yields] D[sup 0][pi][sup+]. Preliminary measurements of the branching fractions of the above hadronic decays are obtained. Preliminary estimates of fractions and phases for resonant and nonresonant contributions to the Dalitz plot are also presented.

Book Description
Preliminary results are presented from the first large-statistics partial wave analysis of K−? system produced in the reaction K{sup -p {yields} K−??−?°p at 11 GeV/c observed with the LASS spectrometer at SLAC. The analysis is based on the moments of the joint angular distributions of the decay to the K−?} system, with subsequent? decay to?+?−?0. The resulting J{sup P} = 2−, 2+ and 3− amplitudes exhibit resonant behavior, and are discussed in the context of the relevant Briet-Wigner fits.
