搜索光子签名的规范介导的超对称性破缺的广义模型的动机。这项研究利用了ATLAS探测器在LHC上记录的质子-质子碰撞数据，并探索了由超对称伙伴态的强和电弱产生主导的模型。四个实验签名结合一个孤立的光子和显着的失踪横向动量进行了探讨。这些特征包括额外的光子，轻子，-夸克喷流，或喷流活动与任何特定的潜在夸克味无关的事件。未观察到显著超出标准模型预测的事件，并设置了模型依赖的95%置信水平排除限值。
A search is presented for photonic signatures motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use ofof proton-proton collision data atrecorded by the ATLAS detector at the LHC, and explores models dominated by both strong and electroweak production of supersymmetric partner states. Four experimental signatures incorporating an isolated photon and significant missing transverse momentum are explored. These signatures include events with an additional photon, lepton,-quark jet, or jet activity not associated with any specific underlying quark flavor. No significant excess of events is observed above the Standard Model prediction and model-dependent 95% confidence-level exclusion limits are set.
