On Yangian Symmetry in Planar N=4 SYM

arXiv:1004.5423 · doi:10.1142/9789814350198_0039

Abstract

Planar N=4 supersymmetric Yang-Mills theory appears to be perturbatively integrable. This work reviews integrability in terms of a Yangian algebra and compares the application to the problems of anomalous dimensions and scattering amplitudes.
