大型强子对撞机上的ATLAS探测器被用来利用收集的数据来寻找轻子味道破坏过程的碰撞。在-玻色子质量处寻找不变质量谱中的增强。数据样本中产生的玻色子的数量是使用类似拓扑的事件来估计的，并且显著减少了测量中的系统不确定性。没有证据表明-玻色子质量的增强，导致分支分数的上限，在95%的置信度水平。
The ATLAS detector at the Large Hadron Collider is used to search for the lepton flavor violating processincollisions usingof data collected at. An enhancement in theinvariant mass spectrum is searched for at the-boson mass. The number ofbosons produced in the data sample is estimated using events of similar topology,and, significantly reducing the systematic uncertainty in the measurement. There is no evidence of an enhancement at the-boson mass, resulting in an upper limit on the branching fraction,at the 95% confidence level.
