The COMPASS experiment at CERN

摘要
To investigate the gluon polarisation of the nucleon the COMPASS experiment is being set up at the CERN muon beam. Using polarised deep inelastic scattering the experiment exploits open charm production and correlated high pT hadron pairs to tag photon gluon fusion. The expected precision for the measured asymmetries will allow a significant determination of the gluon polarisation for x g≈0.1.
