The COMPASS experiment at CERN (SPS, North area, M2 beamline), as part of its programme addresses the exploration of the spin structure of the nucleon by measuring spin (in)dependent azimuthal asymmetries in semi-inclusive DIS and, recently, also in Drell-Yan processes. Between 2002 and 2011 COMPASS performed a series of SIDIS measurements, using a longitudinally polarized muon beam impinging...

We discuss various aspects of azimuthal asymmetries in the Drell-Yan process, focusing on the role of perturbative-QCD calculations. We address both the fixed-target and the collider regime. Furthermore, we present new pQCD predictions for the Drell-Yan cross section averaged over the azimuthal angle, where we discuss the role of QCD threshold resummation.

The angular distributions of Drell-Yan charged lepton pairs in the vicinity of the Z-boson mass peak probe the underlying QCD dynamics of Z-boson production. This talk presents measurements from ATLAS and CMS collaborations on the set of angular coefficients A0-Α7 describing these distributions using pp collisions at √s=8 TeV at the LHC. The measurements are compared to the QCD predictions at...
