Abstract

I will review a recent progress in computing scattering amplitudes in strongly coupled gauge theories — a fascinating subject which has been recently boosted by the formulation of the gauge/string duality in maximally supersymmetric Yang–Mills theory. In addition to the conventional symmetry of the underlying Lagrangian, the scattering amplitudes in this theory exhibit a new, dual superconformal symmetry. This symmetry is powerful enough to completely determine the scattering amplitudes for arbitrary coupling in a suitably defined limit.

Based on the talks given at the Workshop "Crossing the boundaries: Gauge dynamics at strong coupling", 14–17 May 2009, FTPI, University of Minnesota and at the Workshop "Recent Advances in Perturbative QCD and Hadronic Physics", 20–25 July 2009, ECT*, Trento.
