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.

Sumario: | 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 measurements for $W^+$, $W^-$ and $Z/\gamma^*$ boson production, reaching unprecedented precision and strong constraints on parton distribution functions, in particular the strange quark density. Studying jet production in association with a vector boson, perturbative QCD predictions can be tested in a multi-scale environment. Once the QCD aspects of the vector boson production are understood, high precision measurements aim at the tests of the electroweak sector, such as measuring the $W$ boson mass. Here, a selection of recent ATLAS measurements, as presented at the \emph{21st Particles and Nuclei International Conference}, in September 2017 in Beijing, China, is discussed. |
