Abstract:
In this introductory seminar I will present a simple recursive method for computing tree level scattering amplitudes in field theory. The method is solely based on classical equations of motion, without any input from Feynman diagrams. I will present a series of examples involving the scattering of scalars, gluons, and gravitons. Finally, I will discuss some work in progress on how this construction generalizes in two ways. The first concerns curved backgrounds, in particular (Anti) de Sitter spaces. The second generalization is about a recursive recipe for computing loop amplitudes.
The seminar will be held in the conference hall in the building of the Institute of Physics, Na Slovance 2, Prague 8 on the ground floor.
