Georgios Papathanasiou (DESY): All-order amplitudes at any multiplicity in the multi-Regge limit
Maximally supersymmetric Yang-Mills theory serves as a unique theoretical laboratory connecting beautiful mathematics to realistic applications. In this talk I present a complete perturbative solution for the planar scattering amplitudes of the theory at any loop order and multiplicity, in certain region of the conceptually important multi-Regge limit. I describe how the expected integrability of the theory, and analytic structure of amplitudes in the limit, are key for arriving at this solution. Finally, I sketch a proof of the maximal transcendentality principle as an application.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
