W and Z physics with the ATLAS detector
Résumé
We present measurements involving W and Z boson production in pp collisions at √s=7 TeV with an integrated luminosity of ∼35 pb −1 recorded by the ATLAS detector at the Large Hadron Collider. Several analysis are presented: Drell-Yan W → ℓν and Z/γ ∗ → ℓℓ (ℓ = e, µ) production cross sections, muon charge asymmetry from W boson decays, production of jets in association with a Z/γ ∗ boson in the final state and diboson production (W γ ,Z γ ,W +W − ). The measurements are compared to perturbative QCD predictions with various parton distribution functions.
