We show within a geometrical model developed in earlier papers that multiplicity distributions are cut off at large multiplicities. The position and motion of the cut-off point is related to geometrical- and KNO scaling and their violation, in particular by the rise of the ratio $σ_{el}/σ_{t}.$ At the LHC energies a change of the regime, connected with the transition from shadowing to antishadowing is expected.
A behavior of the nucleon structure functions in the resonance region is investigated. Expressions for resonance production form factors, dependent on photon virtuality $Q^2$, which have correct threshold behavior and take into account available data on resonance decays, are obtained. Contributions of resonances to nucleon structure functions are calculated. Obtained expressions are used to investigate the quark-hadron duality in the electron-nucleon scattering processes with the structure function $F_2$ as an example.
It is shown that in a supercritical pomeron model the contribution of the tirple-pomeron diagrams violates the unitarity bound for cross-section even with account of the multiple pomeron exchanges between the initial hadrons. Asymptotic behaviour of the single diffractive dissoci\-ation cross-section is calculated in the approximation where every pomeron in the $3P$-diagram is eikonalized as well as an elastic interaction of initial hadrons is taken into account. In this approximation $σ^{SD}/σ_{tot}\rightarrow 0$ at $s\rightarrow \infty.$
Recent data on single diffraction dissociation, measured by the CDF at the Tevatron show a moderate increase with energy of the cross section, thus confirming the predictions based on the dipole pomeron model.
