Description
In this talk I will present some work in progress on the interplay between scattering amplitudes in N=4 SYM and the Yang-Baxter equation. I will start by reviewing the notions of Yangian symmetry and Grassmannian formulation and recall the recently observed connection between the leading part of the dilatation operator for the integrable spin chain and the tree-level amplitudes. I will then merge these concepts and present the spectral parameter deformation of scattering amplitudes and the interpretation of the spectral parameter itself. Finally I will discuss the possibility of a new (spectral) regularization for loop amplitudes.
