Determination of the Weak Neutral Current Coupling Constants and Limits on the Electromagnetic Properties of the Muon Neutrino

摘要

The goal of this thesis is to determine experimentally the cross section for nu/sub mu /e -> nu/sub mu /e scattering from a sample of over 100 expected nu/sub mu /e implies nu/sub mu /e events collected by the E734 neutrino detector in BNL wide band neutrino beam. By combining these results with results from an anti-neutrino determination of the cross section for anti nu/sub mu /e -> anti nu/sub mu /e scattering in the form of a ratio of cross sections, the weak coupling constants for the electron, g/sub V/ and g/sub A/ can be determined in a model independent way to within a four fold ambiguity where three of the ambiguities can be eliminated by results from e sup + e sup - experiments. The predictions of the Standard Model for the weak coupling constants can then be tested and a precise determination of the electroweak mixing parameter, sin sup 2 theta/sub W/ can be made.
