Abstract
Tree amplitudes of any gauge theory and gravity can be factorized into primitive three-particle amplitudes by the BCFW recursion relations. We show that the amplitudes at any perturbation order are given by tree amplitudes with additional pairs of particles in the forward limit. As an example we compute the four-gluon all-plus helicity amplitude at next-to-leading order.
