MHV diagrams and tree amplitudes of gluons

Abstract

Recently, a new perturbation expansion of gauge theories using MHV amplitudes as vertices was introduced. This alternative to Feynman diagrams is known as MHV diagrams. In this talk I discuss the definition of MHV diagrams for tree-level amplitudes of gluons. This new technique gives a simple and systematic method of computing amplitudes of gluons and makes their twistor space structure manifest.
