Status and Prospects of Theoretical Predictions for Weak Gauge Boson Production Processes at Lepton and Hadron Colliders

摘要

For the envisioned precision measurement of the W-boson mass at present andfuture lepton and hadron colliders it is crucial that the theoreticalpredictions for the underlying production processes are well under control. Webriefly describe the status of the predictions for the W-pair-productionprocesses at e+ e- colliders, e+ e- -> W+ W- -> 4f, and for W- and Z-bosonproduction at pp and p anti-p colliders, pp, p anti-p -> W -> l nu_l and pp, panti-p -> Z,gamma -> l+ l- (l=e,mu). We also discuss the theoreticalimprovements needed to meet the experimental accuracies one hopes to achieve infuture experiments.
