Abstract.Results for the spin structure of the nucleon from the COMPASS data taking periods 2002 to 2004 are presented. The quark contribution to the nucleon spin, following from a QCD fit to the new data, turns out to be significantly larger than it was derived from the previous world data. The new data favour, on the other side, a comparatively small gluon polarisation in the range xg ≈ 0.1. In the data taken with the deuteron target polarised transversely the related asymmetries are found to… Expand
