Two hadron production in longitudinally polarized lepton nucleon collisions — •Christof Hendlmeier, Marco Stratmann, and Andreas Schaefer — Institut fuer Theoretische Physik, Universitaet Regensburg, 93040 Regensburg

We consider the photoproduction of two hadrons in polarized lepton nucleon collisions in the framework of perturbative QCD. This process is studied experimentally at COMPASS (CERN) or HERMES (DESY). The goal of these studies is to extract the polarization Δ g of gluons in the nucleon, which is still largly unknown at the moment and to quantify the theoretical errors.
