Factorization of Multi-Regge Amplitudes. II
Johannes Weis · Physical review. D. Particles, fields, gravitation, and cosmology/Physical review. D. Particles and fields · 1972
Some general comments are made on the relationship between the factorization of multi-Regge amplitudes and the singularity structure of multiparticle amplitudes. A close relationship is found to exist between the validity of factorization and the absence of simultaneous discontinuities in overlapping variables suggested by the Steinmann relations.
