Loop Amplitudes and Quantum Homotopy Algebras

Loop Amplitudes and Quantum Homotopy Algebras

Abstract We derive a recursion relation for loop-level scattering amplitudes of La- grangian field theories that generalises the tree-level Berends-Giele recursion relation in Yang-Mills theory. The origin of this recursion relation is the homological perturbation lemma, which allows us to compute s...
