Transverse Spin Effects In Diffractive Hadron Leptoproduction

Abstract

We consider double spin asymmetries for longitudinally polarized leptons and transversely polarized protons in diffractive vector meson and $Q\bar{Q}$ production at high energies within the two-gluon model. The asymmetry predicted for meson production is quite small. The $A_{lT}$ asymmetry for $Q\bar{Q}$ production contains two independent terms which are large and can be used to obtain information on the polarized gluon distributions in the proton.
