Auditorium (Annecy-le-Vieux)

In this talk I will present work in progress on the interplay between scattering amplitudes in N=4 super Yang-Mills and integrability. After a review of the main ingredients which will be used, including Yangian symmetry and Grassmannian formulation, I will present the spectral-parameter deformation of scattering amplitudes. I will then discuss the interpretation of the spectral parameter itself and the possibility of a new regularization method for loop amplitudes.
