Abstract

We discuss diffractive hadron leptoproduction in terms of skewed gluon distributions and within two-gluon exchange model. Connection of the two-gluon approach with skewed gluon distributions is found. The double spin asymmetries for longitudinally polarized leptons and transversely polarized protons in diffractive vector meson and QQˉQ \bar Q production at high energies within the two-gluon model is analysed. The asymmetry predicted for meson production is found to be quite small. The AlTA_{lT} asymmetry for QQˉQ \bar Q production is large and can be used to obtain information on the polarized skewed gluon distributions in the proton.
