Precision measurements of Standard Model parameters and Re- view of Drell-Yan and vector boson plus jets measurements with the ATLAS detector

The inclusive productions of the $W$ and the on- or off-shell $Z/\gamma$* 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-chromo-dynamics (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, tests soft re-summation 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 state 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.
