QCD instantons in high energy diffractive scattering: Instanton model of Pomeron
Abstract
The role of the QCD vacuum effects in high energy diffractive quark-quark and quark-antiquark scattering is studied with the Instanton Liquid Model. The special attention is given to the problem of formation of the soft Pomeron. We show that in the leading approximation in instanton density the C-odd instanton contribution to the diffractive amplitude is suppressed as 1/s compared to the C-even one.
