Description
COMPASS is a fixed-target experiment located at the CERN SPS, which has been collecting data since 2002. One of the key aspects of the broad COMPASS physics program is the investigation of the transverse-momentum and transverse-spin structure of the nucleon, which has been pursued via measurements of semi-inclusive deep inelastic scattering using a 160 GeV/c muon beam and transversely polarized and unpolarized proton and deuteron targets, and of the Drell-Yan process using a 190 GeV/c pion beam and a transversely polarized proton target. An overview of the main COMPASS results on TMD observables obtained so far is presented.
