What is the iε for the S-matrix? [E-Book] / by Holmfridur Sigridar Hannesdottir, Sebastian Mizera.
This book provides a modern perspective on the analytic structure of scattering amplitudes in quantum field theory, with the goal of understanding and exploiting consequences of unitarity, causality, and locality. It focuses on the question: Can the S-matrix be complexified in a way consistent with...
