The inclusive productions of the W and the on- or off-shell Z/γ* bosons are standard candles at hadron colliders, while the productions of light and heavy-flavour jets in association with a W or a Z boson are important processes to study quantum-chromodynamics (QCD) in multi-scale environments. The measurements of their production cross-sections integrated and differential in several variables have been measured at 7 and 8 TeV centre-of-mass energies and are compared to high-order QCD calculations and Monte Carlo simulations. These measurements have an impact on our knowledge of the parton densities of the proton, and test soft resummation effects and hard emissions for small and large momentum transfers and in multi-scale processes. Precision measurements of fundamental Standard Model parameters in Drell-Yan final states are also performed to describe the angular distributions of the decay lepton.
Run-1 studies carried out by the ATLAS Collaboration are re-viewed and first LHC Run-2 results are included.
