Factorized scattering (source code)

= Factorized scattering

Multiparticle <quantum scattering> is factorized when it decomposes into two-body scatterings without particle production or a new irreducible many-body amplitude. The independence of the answer from the order of exchanges imposes the <Yang-Baxter equation>. Classical <pairwise additivity of soliton shifts> is a corresponding property of integrable <soliton> collisions.
