The Structure of Multiloop Amplitudes in Gauge and Gravity Theories
Z. Bern, J. J. M. Carrasco, H. Johansson
We review the recently discovered duality between color and kinematics in gauge theories. This duality leads to a remarkably simple double-copy relation between diagrammatic numera…

Perturbative Quantum Gravity as a Double Copy of Gauge Theory
Zvi Bern, John Joseph M. Carrasco, Henrik Johansson
In a previous paper we observed that (classical) tree-level gauge theory amplitudes can be rearranged to display a duality between color and kinematics. Once this is imposed, gravi…
