Thomas Pochart - Haag-Ruelle scattering theory and the single-particle problem in the Wightman fram.

The recordings from the third hybrid event for the trimester on Flavors of amplitude , held on February 04, 2026 Speaker: Thomas Pochart (CPhT, École polytechnique, Palaiseau, France.) Title: Haag-Ruelle scattering theory and the single-particle problem in the Wightman framework Abstract: In this presentation, I will first review what purposes axiomatic quantum field theory serves and what the Wightman framework is and achieves. With that being done, I will address the question of the existence of the S-matrix in this framework, following a modern and dimension-independent approach to the Haag–Ruelle scattering; in doing so, I will put a special emphasis on the single-particle problem. With all this discussion having taken place in flat space, I will conclude by presenting some ongoing work on an AdS space version of these arguments.
