Livia Ferro (HU-Berlin)

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.
