Some applications of soft theorems: new recursion relations and N=4 SYM in the Coulomb branch

by Congkao Wen (INFN Rome)

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.
