Dualities for scattering amplitudes in planar N=4 SYM
Paul Heslop
(Durham)
Abstract:
I will review weak-weak dualities relating scattering amplitudes to Wilson loops on the one hand and correlation functions of gauge invariant operators on the other. The Wilson loop / amplitude duality has lead to both numerical and analytic results for MHV scattering amplitudes at two-loops and beyond, including the determination of two loop MHV n-point scattering amplitudes for any n in a certain kinematical regime. The duality with correlation functions has been extended to all scattering amplitudes in the theory and we give explicit examples illustrating this.
