Only a few of them have been given author entries in addition to the Collaboration. en dc.description.abstract We present studies of W and Z bosons with associated high energy photons produced in pp collisions at s=7 TeV. The analysis uses 35 pb−1 of data collected by the ATLAS experiment in 2010. The event selection requires W and Z bosons decaying into high p T leptons (electrons or muons) and a photon with E T > 15 GeV separated from the lepton(s) by a distance ∆R(l, γ) > 0.7 in η-ϕ space. A total of 95 (97) pp → e ± νγ + X(pp → μ ± νγ + X) and 25 (23) pp → e + e − γ + X(pp → μ + μ − γ + X) event candidates are selected. The kinematic distributions of the leptons and photons and the production cross sections are measured. The data are found to agree with Standard Model predictions that include next-to-leading-order O(αα s ) contributions. en_US dc.language.iso eng eng dc.publisher Springer en_US dc.rights.uri http://www.springer.com/open+access/open+choice?SGWID=0-40359-0-0-0 eng dc.subject Hadron-Hadron Scattering eng dc.title Measurement of W and Z production in proton-proton collisions at p s = 7 TeV with the ATLAS detector en_US dc.type Peer reviewed dc.type Journal article dc.description.version publishedVersion en_US dc.rights.holder ©The Author(s) 2011 en_US dc.identifier.doi https://doi.org/10.1007/jhep09(2011)072 dc.subject.nsi VDP::Mathematics and natural science: 400::Physics: 430 en_US dc.subject.nsi VDP::Mathematics and natural science: 400::Physics: 430::Nuclear and elementary particle physics: 431 en_US
