Measurement of W γ and Zγ production in proton-proton collisions at √s = 7 TeV with the ATLAS detector

Abstract

We present studies of W and Z bosons with associated high energy photons produced in pp collisions at √s = 7TeV. The analysis uses 35 pb 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(ααs) contributions. © SISSA 2011.
