New relations for graviton-matter amplitudes

Jan Plefka, Humboldt-Universität, Berlin

We review our recent work on the efficient construction of tree and one-loop scattering amplitudes involving gravitons. The general complexity of perturbative gravity will be discussed and recent insights on rewriting gravitational scattering amplitudes as a double copy of Yang-Mills theories reviewed. Then our results on expanding amplitudes involving gravitons into a basis of only gluon (or more general gluon-matter) amplitudes will be reviewed. Finally, the construction of all rational Einstein-Yang-Mills amplitudes at one-loop order shall be exposed.
