This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The authors have measured production fractions and spectra for [pi]{sup {+-}}, K{sup {+-}} and p, and production spectra for K° and [Lambda]° in both hadronic Z° decays and a Z° → light quark (uds) subset at SLD. The SLD Cherenkov Ring Imaging Detector was used to identify charged hadrons. The CCD vertex detector was used to select the enriched uds sample. For the global sample, the results are consistent with previous experiments. The authors observe a clear flavor dependence in production spectra, but only a small effect in hadron fractions and [xi] = ln(1/x{sub p}) peak positions.

Book excerpt: E777 at the Brookhaven AGS has published a final branching ratio limit for the lepton family violating decay K →?+?+e− of 2.1 × 10−1° (90% C.L.). New results based on approximately 500 events of the G.I.M. suppressed decay K+ →?+e+e− have yielded a branching ratio of (2.75 {plus minus} 0.23 {plus minus} 0.13) × 10−7 assuming a vector interaction with, a form factor = 0.105 {plus minus} 0.035 {plus minus} 0.015. The branching ratio times decay probability for K° →?+ X°, ° → e+e− was found to less than 1.5 × 10−8 (99% C.L.) in the e+e− invariant mass range of 150 to 340 MeV/c. An approved second generation experiment sensitive to K+ →?+e− at the 10−12 level is discussed. 5 refs., 3 figs.
