Precision measurements with electroweak boson in the final state with the ATLAS detector

Measurements of the Drell-Yan production of $W$ and $Z/ \gamma^{*}$ bosons at the LHC provide a benchmark of our understanding of perturbative QCD and probe the proton structure in a unique way. The ATLAS collaboration has performed new high precision measurements for $W^{+}$, $W^{-}$ and $Z / \gamma^{*}$ bosons integrated and as a function of the boson or lepton rapidity and the $Z / \gamma^{*}$ mass. Unprecedented precision is reached and strong constraints on Parton Distribution Functions, in particular the strange density are found. When also studying jet production in association with vector bosons, perturbative QCD prediction in a multi-scale environment can be tested. In this talk, we will also review the latest results, including heavy flavored quarks in the final states, based on proton-proton collision data taken at center-of-mass energies of 8 TeV and 13 TeV. In this context, a dedicated study on splitting scales of the $k_t$ jet-clustering algorithm will be shown. All measurements are compared to state-of-the art theory predictions.
