The relationship of diffractive dissociation to multiperipheral dynamics is explored within the framework of the ABFST model. After splitting the kernel of the integral equation into “resonance” and “Pomeranchuk” components, a variational technique is employed to treat the Pomeranchuk component as a small perturbation. The corresponding perturbed structure of the Fredholm determinant is developed in detail, leading to identification of a small dimensionless parameter η P which measures the strength of the APS branch point and thereby sets the scale of Regge fine structure near J = 1. It is shown that η P also determines the probability of diffractive dissociation into large masses and thus is subject to experimental determination.
