"Multi-Particle Scattering in a Class of Wedge-Local Quantum Field Theories"


Abstract: Wedge-local algebraic quantum field theories (Borchers triples) play an important role in recent operator-algebraic approaches to the construction of quantum field theories. Scattering theory in this setting has so far only been developed up to the two-particle level and a generalization to higher particle numbers was not expected for geometric reasons. In this talk I will explain how to construct n-particle scattering states for a large class of wedge-local QFTs, which includes e.g. Grosse-Lechner type models.
