Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a study of strange vector meson production, [open-quotes]leading particle[close-quotes] effect and a first direct measurement of the strangeness suppression parameter in hadronic decays of the neutral electroweak boson, Z[sup 0]. The measurements were performed in e[sup+]e[sup -] collisions at the Stanford Linear Accelerator Center (SLAC) with the SLC Large Detector (SLD) experiment. A new generation particle ID system, the SLD Cerenkov Ring Imaging Detector (CRID) is used to discriminate kaons from pions, enabling the reconstruction of the vector mesons over a wide momentum range. The inclusive production rates of[phi] and K*[sup 0] and the differential rates versus momentum were measured and are compared with those of other experiments and theoretical predictions. The high longitudinal polarisation of the SLC electron beam is used in conjunction with the electroweak quark production asymmetries to separate quark jets from antiquark jets. K*[sup 0] production is studied separately in these samples, and the results show evidence for the[open-quotes]leading particle[close-quotes] effect. The difference between K*[sup 0] production rates at high momentum in quark and antiquark jets yields a first direct measurement of strangeness suppression in jet fragmentation.

Available in PDF, EPUB and Kindle. Book excerpt: The Mark II detector is used to measure the inclusive production rates for K°, K/sup + -/, rho°, K*° and K*/sup + -/ in a sample of 59,489 hadronic events produced in ee− annihilation at 29 GeV. The inclusive rates for rho° and K*° + anti K*° production for momenta greater than 1 GeV/c are found to be 0.44 +- 0.04 +- 0.06 per event and 0.42 +- 0.05 +- 0.08 per event respectively. The rate for K*/sup + -/ production for momenta greater than 2 GeV/c is found to be 0.26 +- 0.05 +- 0.06 per event. The rate for K° + anti K° production over the full momentum range is found to be 1.27 + 0.03 +- 0.15 per event. The differential production rates for K°, rho° and K*/sup + -/ are, in addition, determined as a function of the particle energy. The inclusive rate for K/sup + -/ is also measured for K/sup + -/ momenta less than 900 MeV/c and is found to be 1.31 +- 0.09 +- 0.19 times the K° + anti K° rate in the same momentum region. These production rates are used to determine the particle content of hadronic events at 29 GeV and are compared to the rates predicted by theoretical models of parton fragmentation. 31 references.

This book was released on 1995-03-29 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 20-year-old problem of the confinement and the resulting spectrum of the bound states is central to quantum chromodynamics (QCD). Many approaches have been tried starting from different points of view: the potential theory, the Bethe-Salpeter equation, string and flux tube models, bag models, vacuum structure, current algebra, lattice theory, and numerical simulations. Phenomenological assumptions and first-principle theoretical results or indications have been combined. Many partial successes have been attained, but a unified and comprehensive treatment is still lacking.In recent years, new attention has been given to the problem, both in terms of theoretical developments and for the purpose of evaluating the spectrum and other properties of the particles. In particular, attention has been focussed on areas like numerical simulations, the derivation of the potential, the use of the Bethe-Salpeter equation, the connection between the potential and the chiral symmetry approach.This workshop was an opportunity for a synthesis and a comparison of the different points of view.
