利用大型强子对撞机ATLAS实验收集的碰撞数据，提出了一种寻找带电轻子风味破坏过程的方法。不变质谱在玻色子质量附近的过剩将是新物理学的一个显著特征。未观察到任何过量，分支分数的上限为95%置信水平，这是迄今为止最严格的限制。
A search for the charged-lepton-flavor-violating processis presented, usingofcollision data collected by the ATLAS experiment at the LHC. An excess in theinvariant mass spectrum near theboson mass would be a striking signature of new physics. No excess is observed, and an upper limitis placed on the branching fraction at 95% confidence level, which is the most stringent limit to date.
