May 13, 2023
In this article an overview is provided of basic concepts, tools, and results of quantum field theoretical scattering theory for massive and massless particles. The appearance of infraparticles in theories with long range forces is also discussed as well as the longstanding problem of asymptotic completeness in quantum field theory.
