Description
COMPASS at CERN is preparing for a new series of measurements on the nucleon structure comprising deep virtual Compton scattering and hard exclusive meson production using muon beams, as well as Drell-Yan reactions using a polarised proton target and a negative pion beam. The former will mainly constrain the generalized parton distribution H and determine the transverse size of the nucleon, while the later measurements will provide information on transverse-momentum dependent (TMD) PDFs. Of particular interest is to verify the predicted change of sign of T-odd TMD PDFs going from DIS to Drell-Yan reactions. The necessary hardware upgrades and the projected results of the programme will be discussed.
