利用LHCb实验在质心能量为7和8 TeV时收集的质子-质子碰撞数据样本进行了轻子味违反衰变的搜索，对应于积分光度为。未观察到显著信号，分支分数的上限设定为90%（95）%置信水平。这些结果提高了目前对这些衰变的最佳限制超过一个数量级。
A search for the lepton-flavor violating decaysis performed using a sample of proton-proton collision data, collected with the LHCb experiment at center-of-mass energies of 7 and 8 TeV and corresponding to an integrated luminosity of. No significant signal is observed, and upper limits on the branching fractions are set asandat 90% (95)% confidence level. The results improve the current best limits on these decays by more than one order of magnitude.
