What is a Resonance?

26.02.2026 14:00 – 15:00

Most particles in nature are unstable, appearing as resonances in scattering processes. In this talk I will explain how resonances can be defined rigorously in terms of the analytic structure of scattering amplitudes, and which properties they satisfy from general principles of quantum field theory. I will emphasize in what sense resonances can be seen as particles, and how their properties can be quantitatively measured via S-matrix bootstrap studies.
