大型强子对撞机上的ATLAS探测器被用来寻找衰减到双电子或双μ子终态的高质量共振。本文给出了在质心能量为8 TeV时，对应于双μ子通道积分光度为的质子-质子碰撞的分析结果。在95%的置信水平下，排除了与费米子耦合的标准模型的窄共振，其中双电子通道中的质量小于2.79 TeV，双μ子通道中的质量小于2.53 TeV，两个通道中的质量小于2.90 TeV。其他模型的解释的限制也提出了，包括一个大统一模型的基础上thegauge群，玻色子，minimalmodels，自旋2引力子激发从兰德尔-Sundrum模型，量子黑洞，和一个最小的步行与复合希格斯玻色子的人工色模型。
The ATLAS detector at the Large Hadron Collider is used to search for high-mass resonances decaying to dielectron or dimuon final states. Results are presented from an analysis of proton-proton () collisions at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity ofin the dimuon channel. A narrow resonance with Standard Modelcouplings to fermions is excluded at 95% confidence level for masses less than 2.79 TeV in the dielectron channel, 2.53 TeV in the dimuon channel, and 2.90 TeV in the two channels combined. Limits on other model interpretations are also presented, including a grand-unification model based on thegauge group,bosons, minimalmodels, a spin-2 graviton excitation from Randall-Sundrum models, quantum black holes, and a minimal walking technicolor model with a composite Higgs boson.
