Yangian symmetry in N=4 super Yang-Mills


Abstract:


Scattering amplitudes in N=4 super Yang-Mills theory have been extensively studied in recent years, due to their remarkable features. In particular, planar amplitudes exhibit a hidden symmetry, the dual superconformal symmetry. I will review how, together with the standard superconformal one, it forms a Yangian structure. Then I will discuss some recent results about the Yangian symmetry of light-like Wilson loops at one loop.
