使用2017-2018年CERN的NA 62实验收集的数据报告了轻子数违反衰变和轻子味违反衰变的结果。没有发现这些衰变的证据，并在90%的置信水平下获得分支比的上限：，和。这些结果改善了1个数量级以上，这些衰减模式的先前结果。
Searches for the lepton number violatingdecay and the lepton flavor violatinganddecays are reported using data collected by the NA62 experiment at CERN in 2017–2018. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% confidence level:,and. These results improve by 1 order of magnitude over previous results for these decay modes.
