Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the measurement of multiplicities and differential cross-sections of the [rho]°, K*°, and [phi] in ee− annihilation at .sqrt.s = 29 GeV, using data collected by the TPC/2.gamma. Detector Facility at PEP. The number of vector mesons per event is determined to be N(/rho/°) = 0.77 +- 0.08 +- 0.15, N(K*° + /bar K/*°) = 0.58 +- 0.05 +- 0.11, and N(/phi/) = 0.076 +- 0.010 +- 0.012. These multiplicities are used to find that the ratio of strange quarks to up quarks produced in the hadronization process is 0.30 +- 0.07, and that the ratio of light vector mesons to all light mesons produced in the hadronization process is 0.45 +- 0.08. All results agree with previous measurements. Measurements are compared with predictions of the Lund and Webber hadronization models, neither model is particularly favored nor disfavored. 60 refs., 32 figs., 24 tabs.

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.

Book excerpt: Data from ee− annihilations at 29 GeV have been used to measure the production and fragmentation of eta mesons. The signal is observed in the eta .-->. .gamma gamma. decay channel. The fragmentation function for p/sub eta/> 1.5 GeV/c agrees well with the shapes predicted by both the Lund and Webber models. However, the mean multiplicity is measured to be = 0.37 +- 0.08 eta mesons per hadronic annihilation event, which is significantly lower than the values predicted by either model. 6 refs., 2 figs., 1 tab.

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°. The measurements were performed in ee− 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? and K*° 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*° 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*° production rates at high momentum in quark and antiquark jets yields a first direct measurement of strangeness suppression in jet fragmentation.

Book excerpt: From hadronic systems induced in 3571 charged-current neutrino-deuterium interactions in the FNAL 15-foot diameter bubble chamber, invariant mass distributions (..pi ... pi..−) and (K/sub s/°..pi../sup + -/) have been used to study inclusive production of vector meson resonances. Inclusive rates from a pure isoscalar target are determined to be 0.05 +- 0.01 K*(890) per charged-current event and 0.19 +- 0.04 rho° per charged-current event. Inclusive K*(890)/sup + -/ production is found to be predominantly K*+(890) in the current fragmentation region. The ratios (rho°/event) from neutron targets and from proton targets separately are, respectively, 0.18 +- 0.06 and 0.21 +- 0.08. For deuteron targets, trends in the dependence of (rho°/event) on variables Y/sub R/, W, p/sub T/, and Q2 are found to be similar to those observed in rho° production from anti ..nu../sub ..mu../p collisions.
