New double soft emission theorems

Year: 2015

Type: article

Abstract: While finding the scattering amplitude for an arbitrary number of particles is a complicated problem in general in quantum field theories, in the limit when one particle is soft (momentum vanishes), the calculations become more tractable. In this paper, the authors find the behavior of the scattering amplitude at tree-level when two particles become soft for a number of theories.
