The asymmetry in the angular distribution of hadronic events produced in the reaction $e\sp+e\sp- \to Z\sp\circ\to$ hadrons at center of mass energies near the mass of the $Z\sp\circ$ is studied. The data used in the analysis were taken at the European Center for Nuclear Research (CERN) from September 1989-August 1990. / The detector was a large multicomponent system consisting of a central Time Projection Chamber, full electromagnetic and hadronic calorimetry, additional tracking near the interaction region, and luminosity monitors. It provided good charged track reconstruction and momentum resolution. / The charge asymmetry is measured through the mean charge flow, $Q\sb{FB}$ averaged over all events, where $Q\sb{FB}$ = $Q\sb{F}$ $-$ $Q\sb{B}$ is the difference between the momentum weighted charges in the forward and backward hemispheres. / A fit to the value of $\langle Q\sb{FB}\rangle$ yields a measurement of $\rm sin\sp2 \theta\sb{W}(M\sbsp{Z}{2})$ = 0.2300 $\pm$ 0.0036(stat.) $\pm$ 0.0015(exp.sys.) $\pm$ 0.0021(theor.sys.), which compares well with values obtained by other methods. Using quark coupling measurements from previous experiments, a value for the electron left-right asymmetry of ${\cal A}\sb{\rm e}$ = 0.122$\sbsp{-0.026}{+0.046}$ is obtained. This result can also be expressed as a measurement of the ratio of the electron vector and axial couplings, / Source: Dissertation Abstracts International, Volume: 52-06, Section: B, page: 3120. / Major Professor: David Levinthal. / Thesis (Ph.D.)--The Florida State University, 1991.

Results are presented on neutral production in (pi)-p interactions at 250 GeV/c. The data was obtained from a 46,000 picture exposure of the liquid hydrogen filled 15 foot bubble chamber at Fermi National Accelerator Laboratory. A total of 22,330 beam interactions and 25,110 candidate gammas were found in the film. Semi-inclusive cross sections were obtained for 2 through 24 charged particle topologies. The production vertex and all associated gammas were measured in 45% of the interactions having one or more candidate gammas. The neutral pion multiplicity distribution was obtained as a function of charged topology and for all charged topologies using the scan information on gamma production. The total neutral pion multiplicity was found to be equivalent to 1/2 the produced charged pion multiplicity. The total (charged plus neutral) non-strange multiplicity distribution was obtained for 0 to 15 particles. The total multiplicity was found to display evidence of oscillatory behaviour with the final state more likely to contain even numbers of particles than odd. Neutral pion longitudinal and transverse momentum and rapidity distributions were obtained from the measured gamma momentum distributions. This experiment was the first hadrom study in the FNAL 15 foot bubble chamber and presents the first data on semi-inclusive neutral pion and total multiplicities at high energies. / Source: Dissertation Abstracts International, Volume: 43-12, Section: B, page: 4030. / Thesis (Ph.D.)--The Florida State University, 1982.

From a sample of 30,400 two prong events the reaction (pi)('+) p (--->) (pi)('+) p (pi)('0) (pi)('0) at 15.7 GeV/c is studied. The data were taken at the SLAC 40'' hybrid bubble chamber with a segmented lead-glass wall placed downstream of the bubble chamber to detect photons and to trigger the bubble chamber upon a deposition of 8 GeV or more of energy. With information from the wall it is possible to reconstruct constrained events with two neutral pions. / The experimental setup and the use of the wall in reconstructing the (pi)('0)'s is described. Invariant masses are presented including the (pi)('0)(pi)('0) mass up to about 4 GeV. No new high mass neutral meson is seen. A van Hove analysis is performed, showing considerable pion diffractive events and production of (DELTA)('++)(1232), f('0)(1270), and (rho)(770). / Events with a (DELTA)('++)(1232) present are isolated and investigated. The cross section for the reaction (pi)('+) p (--->) (DELTA)('++) f('0) (f('0) (--->) (pi)('0)(pi)('0)) is determined to be 25.8 (+OR-) 3.4 microbarns. A moments analysis and amplitude analysis are performed, showing that only S and D wave contributed to the cross section. There is no evidence for the narrow (epsilon)(700), nor for the recently reported f'(1800). / An OPE model calculation is made and compared with data using phase shifts measurements from other experiments. When using phase shifts from Biswas (1981) the model underestimated the cross section below m((pi)('0)(pi)('0)) = 1 GeV, while with phase shifts from Estabrooks and Martin (1974) the model is consistent with the data. / Source: Dissertation Abstracts International, Volume: 44-01, Section: B, page: 0211. / Thesis (Ph.D.)--The Florida State University, 1983.
