Unitarity-based Techniques for One-Loop Calculations in QCD

Abstract

We discuss new techniques developed in recent years for performing one-loop calculations in QCD, and present an example of results from the process 0 -> V q q-bar g g. Talk presented at the 1996 Zeuthen Workshop on Elementary Particle Theory, "QCD and QED in Higher Order", Rheinsberg, Brandenburg, April 21-26, 1996.
