Abstract
A study is made for representations of a production amplitude in exceptional regions inside the physical region. We find that a complete set of independent invariant variables is not sufficient to describe production processes involving more than five external particles, in the exceptional regions. Our result not only influences kinematic singularities as well as the meaning of analyticity of production amplitudes, but also provides a guideline for proposing models and for fitting data. An approach, related to some of these problems, is suggested so that particle distributions for inclusive reactions can be studied with the multi-Regge expansions for all coupling schemes (configuration diagrams).
