实验发现的大的“µ”混合表明，在带电轻子扇区中类似的混合可能是实质性的。我们考虑的可能性是，如果高强度的μ子束，也许是在μ子或中微子工厂的早期阶段，撞击核目标，那么一些μ子转化为tau轻子可能会发生（类似于在MECO中μ子转化为电子）。利用目前对稀有tau衰变的实验限制来限制相关算子的大小，我们发现一个50 GeV的μ子束，每年有10个20 μ子在目标上，可以产生多达10.7µ+ N ！每年+ N个活动。背景可能是实质性的，我们对发现这一进程的可能性发表评论。
The experimental discovery of large �µ �� mixing indicates that analogous mixing in the charged lepton sector could be substantial. We consider the possibility that if a high intensity muon beam, perhaps at the early stages of a muon or neutrino factory, strikes a nuclear target, then conversion of some of the muons into tau leptons could occur (similar to the conversion of muons to electrons at MECO). Using current experimental limits on rare tau decays to bound the size of the relevant operators, we find that a 50 GeV muon beam, with 10 20 muons on target per year, could yield as many as 10 7 µ + N ! � + N events per year. Backgrounds could be substantial, and we comment on the possibility of detection of this process.
