 Title: QCD scattering amplitudes beyond Feynman diagrams

Abstract: Several new methods for the calculation of QCD scattering amplitudes
have been developed in the past years, for instance a new diagrammatic
expansion by Cachazo, Svrcek and Witten and recursive methods by Britto,
Cachazo, Feng and Witten. I review these developments and discuss the
extension towards amplitudes with massive particles.
