The asymmetry in the angular distribution of Drell–Yan dilepton pairs produced in collisions where just one nucleon is transversely polarised has been examined in the literature with a variety of results, mainly diﬀering by factors of two. We re-evaluate the asymmetry via twist-3 contributions in collinear factorisation. In order to allow complete and in-depth comparison with existing calculations, we supply all calculational details.
