On S-Matrix factorization of the Landau-Lifshitz model
Abstract
We consider the three-particle scattering S-matrix for the Landau-Lifshitz model by directly computing the set of the Feynman diagrams up to the second order. We show, following the analogous computations for the non-linear Schr\"odinger model, that the three-particle S-matrix is factorizable in the first non-trivial order.
