- What is the theoretical basis for expecting a change in sign of the Sivers’ function when probed with Drell-Yan scattering? Whatare the implications of an experimental evidence for no sign change?
- Is there only a sign change, with a universal magnitude for the Sivers’ function?
- How much do we know the shape of the Sivers’ function? In order to reconcile the outcome of calculations in TMD- and collinear-factorization, does the Sivers’ function need to have a node?
- What do violations of the Lam-Tung relation for Drell-Yan imply, in general and in terms of TMD?
- What can be measured about the structure of the pion and kaon with Drell-Yan?
- How is the EMC effect manifest in Drell-Yan scattering?
- What is the underlying mechanism of the generation of the hadron’s sea quark distributions?
While the first of these questions are focused on polarized
Drell-Yan experiments, it is important to remember that
there still remain issues of hadron structure that can only
be directly addressed with unpolarized (or polarization
averaged) Drell-Yan measurements.
