International workshop on gauge and string amplitudes

30 Mar 2009, 10:30 → 3 Apr 2009, 18:00 Europe/London

The meeting will focus on new developments in calculational and conceptual aspects of scattering amplitudes. Topics to be discussed include * Scattering amplitudes in gauge theory * On-shell methods (unitarity, MHV rules, recursion relations) * Recent progress in supergravity * Amplitudes and polygon Wilson loops * Applications of string theory * New results for amplitudes in the Standard Model
