Abstract

Using dispersion relations and the properties of Herglotz functions we study solutions of two-Pomeranchukon unitarity in the presence of Castillejo-Dalitz-Dyson (CDD) zeros. We conclude that the best solution is that in which two CDD zeros are present and the triple-Pomeranchukon vertex vanishes linearly. This structure leads to the factorization of cross sections to O(1(lns)2).
