Standard-Model precision measurements with $W$ - and $Z$ -bosons using the ATLAS detector

High-precision measurements by the ATLAS Collaboration are pre-sented using data that were collected in proton-proton collisions at the LHC atseveral centre-of-mass energies. W$^+$, W$^−$ and $Z/γ∗$ production cross-sections are measured at √s= 7 and 13 TeV. Ratios of top-quark pair to Z-boson cross-sections measured from proton-proton collisions at the LHC centre-of-mass energies of √s= 13, 8 and 7 TeV are also presented. Finally, a measurement of the massof the W-boson is also presented based on the 7 TeV dataset with an integratedluminosity of 4.6 fb−1.
