Description
Since a long time the Drell-Yan (DY) process is considered to be a powerful
tool to study hadron structure. In the past, several experiments were successfully
carried out using unpolarised beams and targets. Nowadays, taking into account
the much advanced understanding of the spin structure of the nucleon, we are
discussing a new generation of DY measurements using polarised beams and/or
targets.
The COMPASS collaboration is currently preparing a proposal for future studies of
nucleon structure beyond 2011. One of the main aims is a first measurement of
transverse-momentum-dependent parton distributions (TMDs) using the Drell-Yan
process on a transversely polarised proton target hit by a pion beam. Among
the distributions to be studied are Sivers, Boer-Mulders and pretzelosity TMDs
as well as transversely polarised quark distributions.
The workshop will review ongoing theoretical and experimental efforts related
to the Drell-Yan process. Detailed presentations and discussions of the theoretical
aspects will be complemented by descriptions of planned fixed-target and collider
experiments.
