Polarised Drell-Yan at COMPASS

The COMPASS experiment at CERN took the polarised Drell-Yan data in 2015. The muon pairs originating from 190 GeV/c pion collisions with polarised protons provide a way of accessing the transverse momentum dependent parton distribution functions of the nucleon. The study of the azimuthal spin asymmetries in Drell-Yan complements a wealth of results already obtained from transversely polarised semi-inclusive deep inelastic scattering at COMPASS.The first results from the polarised Drell-Yan measurements will be shown in the context of the previously obtained SIDIS results. The expected impact of these data will be discussed, as well as prospects for future Drell-Yan related studies.
