Book Description
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.

Book Description
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.
