Yangian symmetry of scattering amplitudes and the dilatation operator in N=4 supersymmetric Yang-Mills theory.

Brandhuber, Andreas and Heslop, Paul and Travaglini, Gabriele and Young, Donovan (2015) 'Yangian symmetry of scattering amplitudes and the dilatation operator in N=4 supersymmetric Yang-Mills theory.', Physical review letters., 115 (14). 141602 .

Abstract

It is known that the Yangian of PSU(2,2|4) is a symmetry of the tree-level S matrix of N=4 super Yang-Mills theory. On the other hand, the complete one-loop dilatation operator in the same theory commutes with the level-one Yangian generators only up to certain boundary terms found by Dolan, Nappi, and Witten. Using a result by Zwiebel, we show how the Yangian symmetry of the tree-level S matrix of N=4 super Yang-Mills theory implies precisely the Yangian invariance, up to boundary terms, of the one-loop dilatation operator.
