The origin of the KLT relations and nonlinear relations for Yang-Mills amplitudes

The origin of the KLT relations and nonlinear relations for Yang-Mills amplitudes

By means of a kinematic analysis of tree level graviton amplitudes we find, at least through six points, that the reason of their decomposition as a sum over products of gauge boson amplitudes is on-shell gauge invariance and unitarity. As a by-product of our analysis we find nonlinear relations obe...
