Description
We consider the photoproduction of two hadrons in polarized lepton-nucleon
collisions in the framework of perturbative QCD. After illustrating how to
obtain the experimentally relevant observables a detailed phenomenological
study of the photoproduction of hadron pairs at high transverse momenta is
presented. We show theoretical predictions for the relevant cross sections
and double-spin asymmetries at HERMES and COMPASS kinematics as well as
theoretical uncertainties and analyze the sensitivity of the asymmetries
to the gluon polarization delta g in the nucleon.
