Results on the spin structure of the nucleon from COMPASS

Highlights of the nucleon spin studies from the COMPASS experiment at CERN are presented. Three independent measurements of the gluon polarization give values compatible with zero for x close to 0.1. The quark helicity distributions are determined for all flavors. On the transversity side, Collins a...

description Highlights of the nucleon spin studies from the COMPASS experiment at CERN are presented. Three independent measurements of the gluon polarization give values compatible with zero for x close to 0.1. The quark helicity distributions are determined for all flavors. On the transversity side, Collins and Sivers asymmetries are measured for proton and deuteron targets. Plans for COMPASS-II include DVCS as well as polarized Drell-Yan measurements.
