Analytic Properties of Scattering Amplitudes in High Energy Physics

Explore a physics seminar from NYU Physics where Hofie Hannesdottir from the Institute of Advanced Studies delves into the complex relationship between physical principles and scattering amplitudes. Examine how causality and crossing symmetry influence the analytical properties of scattering amplitudes, and discover the connections between different observables through analytic continuations. Learn how these physical insights can be applied to simplify perturbative calculations and enhance understanding of collider observables in high-energy physics.
