Available in PDF, EPUB and Kindle. Book excerpt: We have updated our results on identified charged hadron production using the full SLD data sample of 550,000 hadronic Z° decays taken between 1993 and 1998. The SLD Cherenkov Ring Imaging Detector allows the identification of clean samples of charged pions, kaons and protons over a wide momentum range, providing precise tests of perturbative QCD calculations and of fragmentation models. We have studied flavor-inclusive Z° decays, as well as decays into light, c and b flavors, selected using the SLD vertex detector. In addition we have updated our comparison of hadron and antihadron production in light quark (rather than antiquark) jets, selected using the high SLC electron beam polarization. Differences between hadron and antihadron production at high momentum fraction provide precise measurements of leading particle production and new, stringent tests of fragmentation models.

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.

Download or read book The Production of pi sup K sup P K and Lambda in Hadronic Z Decays written by and published by . This book was released on 1995 with total page 5 pages. 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 improved measurements of the differential production rates of stable charged particles in hadronic Z{sup 0} decays, and of charged pions, kaons and protons identified over a wide momentum range using the SLD Cherenkov Ring Imaging Detector. In addition to flavor-inclusive Z{sup 0} decays, measurements are made for Z{sup 0} decays into light (u, d, s), c and b primary flavors, selected using the upgraded Vertex Detector. Large differences between the flavors are observed that are qualitatively consistent with expectations based upon previously measured production and decay properties of heavy hadrons. These results are used to test the predictions of QCD in the Modified Leading Logarithm Approximation, with the ansatz of Local Parton-Hadron Duality, and the predictions of three models of the hadronization process. The light-flavor results provide improved tests of these predictions, as they do not include the contribution of heavy-hadron production and decay; the heavy-flavor results provide complementary model tests. In addition we have compared hadron and antihadron production in light quark (as opposed to antiquark) jets. Differences are observed at high momentum for all three charged hadron species, providing direct probes of leading particle effects, and stringent constraints on models.

Available in PDF, EPUB and Kindle. Book excerpt: We present a preliminary study of correlations in rapidity between pairs of identified charged pions, kaons and protons in the SLD data. Details of short-range charge correlations between all combinations of these hadron species are used to study the locality of quantum number conservation, and suggest local charge ordering along the entire hadronization chain. A strong long-range K[sup+]-K[sup -]correlation is observed at high-momentum and weaker long-range[pi][sup+]-[pi][sup -], [pi][sup+]-K[sup -] and p-K[sup -] and p[bar p] correlations are observed in light flavor events, providing new information on leading particle production in u, d and s jets. The long-range correlations observed in c[bar c] and b[bar b] events are markedly different and consistent with expectations based on known decay properties of the leading heavy hadrons. The SLC electron beam polarization is used to tag the quark hemisphere in each event, allowing the first study of rapidities signed relative to the quark (vs. antiquark) direction. Distributions of ordered, signed rapidity differences provide a new probe of the fragmentation process, including the first direct observation of baryon number ordering along the q[yields][bar q] axis.

Available in PDF, EPUB and Kindle. Book excerpt: The reactions J/psi .-->. .omega. KAPPA antiKAPPA.pi. and J/psi .-->. phiKAPPA/sup + -/KAPPA/sub S/°.pi./sup - +/ have been studied using a sample of 5.8 x 106 produced J/psi decays. The KAPPA/sup + -/KAPPA/sub S/°.pi./sup - +/ and KAPPA/sup +/KAPPA−.pi.° systems recoiling against an .omega. show enhancements in the mass distribution around 1.445 GeV/c2 with consistent branching ratios. No such structure is observed in the mass distribution of the KAPPA/sup + -/KAPPA/sub S/°.pi./sup - +/ system recoiling against a phi. A comparison of these observations with the corresponding channels in radiative J/psi decays permits a detailed study of the structures seen in the iota(1440) and EPSILON(1420) signal regions. 8 refs., 4 figs.
