Abstract

It is demonstrated that the global properties of the rapidity gap events at HERA can be understood based on electron-gluon scattering and a non-perturbative mechanism of colour neutralization. Using the measured inclusive structure function F₂ to determine the parameters of the parton model, the diffractive structure function F₂^D is predicted. The ratio of diffractive and inclusive cross sections, R_D = σ_D/σ_incl≃ 1/9, is determined by the probability of the produced quark-antiquark pair to evolve into a colour singlet state.
