Spin effects in vector meson and $Q \bar Q$ production

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We study light hadron leptoproduction at small xx. 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 QQˉQ \bar Q production are investigated. The predicted AlTA_{lT} asymmetry is large and can be used to obtain information on the polarized gluon distributions in the proton.
