Universality of the preasymptotics in the hadron and photon diffraction

We note that it is premature to make a conclusion on the multiplicity of the Pomerons on the basis of the available experimental data since the interactions have a preasymptotic natureComment: 4 pages, latex, no figure

Sum rules for spin asymmetries

Starting from rotational invariance we derive sum rules for the single-spin asymmetries in inclusive production and binary processes. We also get sum rules for spin correlation parameters in elastic pp-scattering.Comment: 4 page

Reflective scattering effects in double-pomeron exchange processes

We discuss energy dependence of rapidity gap survival probability in the double-pomeron exchange processes with account of the reflective scattering effects.Comment: 11 pages, 3 figure

Energy dependence of gap survival probability and antishadowing

We discuss energy dependence of gap survival probability which follows from rational form of amplitude unitarization. In contrast to eikonal form of unitarization which leads to decreasing energy dependence of gap survival probability, we predict a non-monotonous form for this dependence.Comment: 9 pages, 3 figures, revised and extended versio

Multiparticle production in the model with antishadowing

We discuss the role of absorbtion and antishadowing in particle production. We reproduce power-like energy behavior of the mean multiplicity in the model with antishadowing and discuss physical implications of such behavior for the hadron structure.Comment: 11 pages, 3 figures, extended version of the talk at the XXXII International Symposium on Multiparticle Dynamics September 7-13, 2002 Alushta, Crimea, Ukrain
