Abstract

We study light hadron leptoproduction at small x. Vector meson production is analysed in terms of generalized gluon distributions with taking into account the transverse quark motion. Within a two-gluon model the double spin asymmetries for longitudinally polarized leptons and transversely polarized protons in the diffractive Q Q production are investigated. The predicted A_lT asymmetry is large and can be used to obtain information on the polarized gluon distributions in the proton.
