Scattering of massless particles: scalars, gluons and gravitons
Scattering of massless particles: scalars, gluons and gravitons
In a recent note we presented a compact formula for the complete tree-level S-matrix of pure Yang-Mills and gravity theories in arbitrary spacetime dimension. In this paper we show that a natural formulation also exists for a massless colored cubic scalar theory. In Yang-Mills, the formula is an integral over …
