Interactions of hadrons and nuclei at superhigh energies and small-x physics

A connection between high-energy interactions of hadrons and nuclei and sma ll x deep inelastic scattering (DIS) is discussed. It is pointed out that a n information on properties of the Pomeron, which was obtained from studies of hadronic interactions is very important for understanding the main feat ures of experimental data on small x DIS. The Quark Gluon Strings Model (QG SM) and the Dual Parton Model (DPM) of high-energy hadronic interactions ar e reviewed and an important role of multi-Pomeron exchanges is emphasized. It is shown that the models, which well describe hadronic interactions are also in a good agreement with recent results on small-x DIS From HERA.
