Extended relations to include effective operator effects.

Enhanced understanding of gauge-gravity amplitude connections.

Abstract

We find new relations for the non-universal part of the Yang-Mills amplitudes by combining the KLT-relation and the soft behavior of gauge and gravity amplitudes. We also extend the relations to include contributions from effective operators.
