CP-tests in high-energy proton-antiproton collisions

A general analysis of CP-violating correlations forW,Z and jet production in proton-antiproton collisions is presented. We consider unpolarizedp, beams, but a polarisation analysis of the producedW's andZ's. New CP-violating interactions beyond the standard model are parametrized by an effective Lagrangian. The bounds obtainable on the parameters of this Lagrangian from measurements are discussed. Finally we point out that a particular combination of polarisation observables of theW's and theZ allows a direct determination of the gluon distribution in the proton if the quark distributions are assumed to be known.
