Recent measurement of $\Delta G/G$ at COMPASS
We present a preliminary measurement of the gluon polarization $\Delta G/G$ in the nucleon, based on the spin asymmetry of quasi-real photoproduction events for which a pair of large transverse momentum hadrons is produced. The data were obtained by the COMPASS experiment at CERN using a 160 GeV pol...
