摘要：
We applied the factorization method to the processes of two-particle scattering with anunstable particle in the intermediate state. It was shown, that in the frame work of this method, the cross-section can be represented in the universal factorized form for an arbitrary set of particles. An exact factorization is caused by a specific structure of unstable particles propagators. Phenomenological analysis of the factorization effect is performed.
