Large-Nc Bootstrap reinforced by Anomalies

22.01.2025 11:30 – 12:30

In this talk I will explore how Unitarity and Causality strongly constrain the landscape of SU(Nc) theories in the Large-Nc limit. I will show how the space of allowed UV completions of the 2-2 pion scattering amplitude reduces to a handful of interesting theories. Successively I will add to the picture anomalies, and derive new bounds on the scale where massive higher spin particles must enter. I will comment on various models and see how they saturate the derived bounds.
