Transversity effects in light meson leptoproduction

Abstract

The light meson electroproduction is analyzed within the handbag approach. We consider the leading-twist contribution together with the transversity effects. We show that the transversity Generalized Parton Distributions (GPDs), $H_T$ and ${\bar{E}}_T$ are essential in the description of spin effects in the pseudoscalar and vector meson leptoproduction.
