摘要：

Order alpha(s) corrections to the diffractive structure functions F-L(D) and F-2(D) at large Q(2) and small x are evaluated in the semiclassical approach, where the initial proton is treated as a classical color field. The diffractive final state contains a fast gluon in addition to a quark-antiquark pair, Two of these partons may have large transverse momentum. Our calculations lead to an intuitive picture of deep inelastic diffractive processes which is very similar to Bjorken's aligned-jet model. Both diffractive structure functions contain leading twist contributions from high-p(perpendicular to) jets.
