摘要：A quantum eld theoretic treatment of inclusive deep{inelastic di ractive scattering is given. The process can be described in the general framework of non{ forward scattering processes using the light{cone expansion in the generalized Bjorken region. Evolution equations of the di ractive hadronic matrix elements are derived at the level of the twist{2 contributions. The di ractive parton densities are obtained as projections of two{variable parton distributions. An analogous formalism applies to the higher twist contributions.
