Abstract

QCD amplitudes are one of the most important ingredients for the understanding of the early universe. In this work we present how the knowledge of the asymptotic states can be used to calculate the scattering amplitude of the underline QCD events at high energy. To do so, we show how the understanding of the soft factorization and the soft structure of amplitudes can provide us all the necessary information to fix the kinematics of amplitudes using inverse soft limit techniques.
