Precision measurements of the Drell-Yan production of W and Z bosons at the LHC provide a benchmark of our understanding of perturbative QCD and electroweak processes and probe the proton structure in a unique way.
The ATLAS collaboration has performed a new precise triple differential cross-section measurement as a function of M(ll), dilepton rapidity and cosθ∗ defined in the Collins-Soper frame. This measurement provides sensitivity to the PDFs and the Z forward-backward asymmetry, AFB, which is derived and will be presented. This builds the foundation for a possible future extraction of the weak-mixing angle.
