QCD EXPECTATIONS FOR DEEP-INELASTIC SCATTERING AT SMALL-X

The basic QCD expectations concerning deep-inelastic scattering at low x, where x is the Bjorken scaling variable are reviewed. This include s discussion of the Lipatov equation which sums the leading powers of ln(1/x) and the shadowing effects. Phenomenological implications of th e theoretical expectations for the deep-inelastic lepton-hadron scatte ring in the small-x region which will be accessible at the HERA ep col lider are described. We give predictions for structure functions F2 an d F(L) based on the k(T) factorization theorem and discuss jet product ion in deep-inelastic lepton scattering. The list of other topical pro blems relevant for small-x physics is given.
