16:00 - 17:00
Room: Albanova FB53 Quantum scattering amplitudes, classically given by the famous pictorial representation of Richard Feynman which describe the many ways the collisions between particles could take place in space-time, are a cornerstone of today's quantum field theory. In the past decade, we have learned a great deal about scattering amplitudes for completely general theories. Central to these developments has been the N = 4 Super- Yang-Mills theory. The quest to more loops, more legs and less symmetry led to completely different ways of visualizing and computing scattering amplitudes, some of which reach beyond the standard framework of flat space relativistic quantum field theory and place quantum scattering amplitudes at the intersection several fields of physics (and mathematics). We shall highlight some of the surprising advances and illustrate them with examples from N=8 supergravity and N = 4 super-Yang-Mills theory, discuss applications to particle physics experiments, two-dimensional integrable models and other observables in quantum field theories.

10:00 String Amplitudes in the High and Low Energy Limits - Rodolfo Russo (Queen Mary)
String Amplitudes in the High and Low Energy Limits
- Rodolfo Russo (Queen Mary)
10:00 - 11:00
Room: Albanova FB52 Perturbative string amplitudes encode information that is relevant in many different contexts, from determining the effective action to studying the high energy behaviour of the theory. I will discuss how to isolate from the full string amplitudes the leading and subleading contributions to these different limits by focusing in particular on some concrete, interesting examples.
