QCD ON-SHELL RECURRENCE RELATIONS FROM THE LARGEST TIME EQUATION
Continuous Advances in QCD 2006
We first give a field theoretical derivation of the tree level on-shell gluon (BCFW) recursion relations, by reassembling the tree level gluon Feynman diagrams in a convenient gauge, space-cone. The significance of these recurrence relations is that they allow obtaining multi-gluon tree level amplitudes from the previously computed lower n-point functions. Our proof of the BCFW recursion relations hinges on an algebraic identity in momentum space which is the Fourier transform of Veltman'sdoi:10.1142/9789812708267_0058 fatcat:3db7nt3ukzfu3p6c7u6amlb3di
