Determination of the gluon contribution to the nucleon spin with COMPASS
New double-spin asymmetry data from the COMPASS experiment at CERN are presented. The data are used to determine the polarized gluon distribution $\Delta G/G(x)$, via three different techniques. Next-to-leading order QCD fits to the nucleon polarized structure functions indicate that the first momen...
