Diffractive hadron production and pomeron coupling structure

Abstract

Large-distance effects, which lead to the spin-flip part of the hadron -pomeron coupling in QCD -models, are discussed. We study spin asymmetries in exclusive reactions and in diffractive $Q\bar{Q}$ and vector meson production which are sensitive to the spin-dependent part of the pomeron coupling.
