Wγ/Zγ production and New Physics constraints in ATLAS

The integrated and differential fiducial cross sections for the production of a W or Z boson in association with a high energy photon are measured. Events are selected using leptonic decays of the W and Z bosons, including the Z->nu nu decay channel. The data are used to test the electroweak sector of the Standard Model and search for evidence for new phenomena. The measurements are used to probe anomalous triple gauge boson couplings and to search for the production of vector resonances decaying to Zgamma and Wgamma.
