Spin asymmetries for events with high $p_T$ hadrons in DIS and an evaluation of the gluon polarization

We present a measurement of the longitudinal spin cross section asymmetry for deep inelastic muon-nucleon interactions with two high transverse momentum hadrons in the final state. Two methods of event classification are used to increase the contribution of the Photon Gluon Fusion process to above 3...
