Regge representations for scatterings which violate the Pomeranchuk theorem are investigated. It is shown that the partial wave amplitudes include Kronecker-delta singularities at J=1. As a model, we consider the case in which two amplitudes are obtained from the matrix N/D method. Analytically continued partial wave amplitudes have CDD singularities when J is decreased, but the two amplitudes are the same for sufficiently large J. For this condition, the inelasticities must have a zero for real t larger than the inelastic threshold and for J between one and two. Using the Reggeized absorption model, we obtain necessary conditions. Factorizability of the terms which violate the Pomeranchuk theorem is shown, and we estimate the amplitudes of violations for ππ,πK and KK scatterings.
