Precision measurements with an 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. Also a new three dimensional cross-section measurement of Z boson vs. its invariant mass, the absolute dilepton rapidity, and the angular variable between the lepton and the quark in the Collins-Soper frame will be discussed. Unprecedented precision is reached and strong constraints on Parton Distribution functions, in particular the strange density are found. When also studying light and heavy quark iniated jet production in association with vector bosons, perturbative QCD prediction in a multi-scale environment can be tested. Once the QCD aspects of the vector boson production are understood, high precision measurements aiming at the tests of the electroweak sector, such as the W boson mass or the forward backward asymmetry in the Z boson productions can be measured. A brief review of the latest results from the ATLAS collaboration will be given.
