The Infrared Structure of Nonlinear Sigma Model Amplitudes

Description:

On-shell formulations of scattering amplitudes for quantum field theories, without utilizating the local descriptions of Lagrangian and Feynman diagrams, have become increasingly useful and important in recent years for both formal and practical reasons. The nonlinear sigma model (NLSM), which describes the interactions between Nambu-Goldstone bosons, is an ideal testing...
