MIRACULOUS HELICITY RULES, BASES, AND AMPLITUDES FOR VECTOR BOSONS

Résumé- Nous décrivons les développements récents de la théorie de perturbation qui résultent de calculs faits sur des réactions avec des bosons de gauge. Abstract- We describe what we have learned in recent years about perturbation theory as a result of doing calculations for processes with gauge bosons. During the past half-dozen years many of us have been doing higher-order Born ampli-tude calculations for quark-gluon processes and for weak-boson production. Among the motives are the interest in multi-jet phenomena in the former case and tests for trilinear couplings in both cases
