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.
