Abstract
Hermes has measured longitudinal double spin asymmetries as a function of transverse momentum pT using charged inclusive hadrons from electroproduction off a deuterium target. At pT>1 GeV, the asymmetries are sensitive to the spin dependent gluon distribution Delta g. To extract the gluon polarization Delta g/g, information on the background asymmetry and the subprocess kinematics has been obtained from a Leading Order Monte Carlo model. Values for Delta g/g have been calculated both as a function of the measured pT and x, using two different methods, in the region pT>1.05 GeV.
