Abstrakt
COMPASS is a fixed-target experiment with wide scientific programme. The main objectives are nucleon structure studies and hadron spectroscopy.
A short overview of the physics programme and the apparatus is given. Then, three measurements that have a relation to quarkonium are highlighted and briefly described: a determination of limits on the exotic resonance Z(c)(+/-)(3900) branching ratio and partial width; study of the gluon Sivers asymmetry in leptoproduction of J/psi resonance and finally the first- ever study of the Drell-Yan process with a transversely polarised target.
