Limits on the diffractive mass in strong coherent γ*-nucleus scattering
Abstract
An evolution equation for diffractive production with a definite rapidity gap is given. Coherent γ*A collisions in the unitarity (saturation) region are studied with the conclusion that the diffractive mass is always on the order of the γ* virtuality, Q, when the scattering is strong. Deep in the saturation region diffractive masses significantly greater than Q are strongly suppressed by a Levin-Tuchin mechanism.
