Abstract

We present unitarity as a method for determining the infinities present in graviton scattering amplitudes. The infinities are a combination of IR and UV. By understanding the soft singularities we may extract the UV infinities and relate these to counterterms in the effective action. As a demonstration of this method we re-derive the UV infinities present at the 1-loop level when gravity is coupled to matter.
