This book was released on 1997 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have measured production rates as a function of momentum of the identified hadrons [pi], K, K°, K*°, [phi], p, [Lambda]° and their antihadrons in inclusive hadronic Z° decays, as well as separately in decays into light, c and b flavors. In addition they have compared hadron and antihadron production rates in light quark (rather than antiquark) jets. The SLD Cherenkov Ring Imaging Detector was used to identify charged hadrons. The vertex detector was used to tag high-purity samples of light- and b-flavor events. The electron beam polarization was used to tag samples of quark and antiquark jets. Clear flavor dependences are observed, consistent with expectations based upon measured production and decay properties of heavy hadrons. They use the light-flavor results to test the predictions of MLLA QCD and of various fragmentation models. Differences between hadron and antihadron production in light quark jets are observed at high momentum fraction, providing direct evidence that higher-momentum particles are more likely to contain a primary quark or antiquark, and they use these results to make a new direct measurement of strangeness suppression in the jet fragmentation process.

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.

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.

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.

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.

Download or read book Preliminary Measurement of Leading Particle Effects in Hadronic Z[sup 0] Decays written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present preliminary evidence for leading particle production in hadronic decays of the Z[sup 0] to light quark pairs using 150,000 events recorded in the SLD experiment at SLAC. The highly polarized electron beam produced by the SLC is used to tag quark and antiquark jets, and a signed impact parameter technique is employed to reject heavy flavor events. Charged hadrons are identified in the SLD Cherenkov Ring Imaging Detector (CRID) and[Lambda]/[bar[Lambda]] are reconstructed using their charged decay modes. In a high purity sample of quark jets, the baryon momentum spectrum is harder that that of the antibaryon, and conversely for a sample of antiquark jets, supporting the hypothesis that the faster particles in jets are more likely to carry the primary quark or antiquark from the Z[sup 0] decay. Similarly, more high momentum K[sup -] that K[sup+] are observed in quark jets and conversely for antiquark jets, consistent with the hypothesis that leading K[sup[+-]] are produced predominantly in s[bar s] events rather than[ital u][bar[ital u]] events.
