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
Deep--elastic scattering and asymptotics
Deep--elastic scattering and its role in discrimination of the possible
absorptive and reflective asymptotic scattering mechanisms are discussed with
emphasis on the difference in the experimental signatures related to production
processes.Comment: 8 pages, no figures, added discussions and reference
