Quark and lepton couplings in the weak interactions
Journal Article

· Phys. Rev., D; (United States)
We present a comprehensive study of the weak neutral-current interactions of u and d quarks and of the electron. A model-independent analysis using data from deep-inelastic, inclusive-pion, elastic, and exclusive-pion neutrino processes provides a unique determination of the u- and d-quark couplings. For electron couplings, neutrino-electron-scattering, atomic-parity-violation, and new polarized-electron-scattering data are discussed. With the assumption of a single Z/sup 0/ boson, we show that the electron couplings are almost uniquely determined. The predictions of the Weinberg-Salam model (for sin/sup 2/theta/sub W/ = 0.20--0.30) are in remarkably good agreement with our results.
