Description
Soft theorems describe the universal behaviors of scattering amplitudes in the limits with some momenta going to zero. In this talk, I will discuss some applications of certain soft theorems. In particular, these soft theorems allow us to derive a set of new recursion relations for a wide range of theories for which the original Britto-Cachazo-Feng-Witten (BCFW) recursion relations cannot apply. I will also discuss applying the soft theorems from spontaneously conformal symmetry breaking to N=4 super Yang-Mills in the Coulomb branch.
