利用原子碰撞测量了高能光子产生玻色子的积分基准截面和微分基准截面。分析使用的数据样本的综合光度的ATLAS探测器在2011年大型强子对撞机数据采集期间收集的。事件的选择使用轻子衰变和玻色子[和]与相关的孤立光子的要求.这些数据被用来测试标准模型的电弱部分，并寻找新现象的证据。这些测量被用来探测反常的、、和三重规范玻色子耦合，以及寻找衰减到和的矢量共振的产生。没有偏离标准模型的预测观察和限制放置在异常的三规范玻色子耦合和生产新的矢量介子共振。
The integrated and differential fiducial cross sections for the production of aorboson in association with a high-energy photon are measured usingcollisions at. The analyses use a data sample with an integrated luminosity ofcollected by the ATLAS detector during the 2011 LHC data-taking period. Events are selected using leptonic decays of theandbosons [and] with the requirement of an associated isolated photon. 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 the anomalous,, andtriple-gauge-boson couplings and to search for the production of vector resonances decaying toand. No deviations from Standard Model predictions are observed and limits are placed on anomalous triple-gauge-boson couplings and on the production of new vector meson resonances.
