Drell-Yan measurements in COMPASS
The future polarized Drell-Yan measurement at COMPASS is presented. The Drell- Yan events produced by the collision of a pion beam with a transversely polarized NH$_{3}$ target will allow to access the transverse momentum dependent parton distribution functions of hadrons.

| Sumario: | The future polarized Drell-Yan measurement at COMPASS is presented. The Drell- Yan events produced by the collision of a pion beam with a transversely polarized NH$_{3}$ target will allow to access the transverse momentum dependent parton distribution functions of hadrons. Sivers, Boer-Mulders, pretzelosity and transversity functions will be studied. This measurement is complementary to the ones performed in COMPASS in semi-inclusive deep inelastic scattering of muons off a transversely polarized target, providing an important test of QCD in the non-perturbative regime. |
