Results on alpha_s and QCD from (and Above) the Z0
ArXiv hep-ex/9709010 (1997)
Abstract:
Measurements of alpha_s from e+e- annihilation experiments are reviewed and compared with measurements from other processes. Highlights are presented of recent QCD studies in e+e- annihilation at the Z0 resonance.Event Orientation in e+e- Annihilation
Proceedings of XIIth International Workshop: High Energy Physics and Quantum Field Theory (1997)
Abstract:
We review the orientation of e+e- \to q\bar q g events in terms of the polar and azimuthal angles of the event plane w.r.t. the electron beam direction. The asymmetry of the azimuthal-angle distribution is, like the left-right forward-backward polar-angle asymmetry, sensitive to parity-violating effects in three-jet events; these are presently being explored experimentally. We present these observables at O(\alpha_s) in perturbative QCD and discuss their dependence on longitudinal beam polarisation and c.m. energy. A moments analysis in terms of the orientation angles allows a more detailed test of QCD by isolating the independent helicity cross-sections.Direct Measurement of Leptonic Coupling Asymmetries with Polarized Z Bosons
