Resumen:
We present studies of W and Z bosons with associated high energy photons produced in pp collisions at 7 TeV. The analysis uses 35 pb-11 of data collected by the ATLAS experiment in 2010. The event selection requires W and Z bosons decaying into high pT leptons (electrons or muons) and a photon with ET > 15 GeV separated from the lepton(s) by a distance R> 0.7 in - eta-phi space. 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( s) contributions.
