Scattering amplitude and its soft decomposition

High Energy Physics - Theory 2023-03-09 v2

Abstract

In the pure scattering theory, the universality of the soft limit has been studied for a long time. In this talk we review the property of soft limit to relate an nn-point amplitude to an (n1)(n-1)-point amplitude. We show how this property can be used to decompose amplitudes into different complementary soft channel. The existence of such decomposition provides a new way to understand how to construct amplitude solely from them soft limit.
