Higher point positivity and large-N QCD

18.06.2026 14:00 – 15:00

Scattering amplitudes provide a powerful way to constrain effective field theories from the bottom-up, using only general physical consistency conditions such as unitarity and causality. Most existing bounds are based on four-point amplitudes. In this talk, I will explain how higher point amplitudes can be used to obtain new constraints that go beyond the four-point analysis. As a concrete example, I will apply the method to Large-Nc QCD.
