Description
Measurements are presented of high energy photons produced in association with W and Z bosons in pp collisions
at √s = 7 TeV using the ATLAS detector. The analysis uses W and Z bosons selected with leptonic (e/µ) decays.
Subsets of these events are identified by demanding an electromagnetic object passing isolated photon selection
criteria. We isolate signals of p + p → l + ν + γ + X and p + p → l + l + γ + X production
with photon ET > 15 GeV and delatR(l -γ ) > 0.7. The production cross sections and the kinematic distributions
of the leptons and photons are compared to Standard Model predictions. The measurements are sensitive to the
electroweak triple gauge couplings of the Standard Model, and constraints are set on anomalous TGCs.
