Structure of the soft theorem toward amplitudes construction

In this paper, we present the importance of soft radiation’s contribution for high-precision physics to match the theoretical predictions with the experimental measurements. We briefly review the different properties of soft factorization in the context of scattering amplitude. The universal behavior of the IR contribution in this factorization plays the central focus of studies in order to recover any information about the UV contribution which allows us to develop an algorithm to softly add particles to compute higher point amplitudes.
