Description

This talk will give an overview on first results on W and Z production in proton-proton collisions at √s=7 TeV, recorded with the ATLAS experiment at the LHC. The selection of W and Z events will be described, together with data-driven methods used to estimate the trigger and reconstruction efficiencies, as well as the main backgrounds. The W and Z signal yields and the extracted cross sections at √s=7 TeV will be presented, as well as preliminary distributions of kinematic variables and first measurements of the W charge and polarization asymmetry.
