在原子核场中进行违反轻子味道的相干介子-电子转换的实验研究，已经被提出达到每停止的介子10^(-16)-10^(-18)的前所未有的灵敏度。在这个水平上，他们探测有效质量尺度远远超过1000TeV的新相互作用。然而，它们必须与普通束缚介子衰变的背景作斗争。为了更好地理解背景谱形状和速率，我们对库仑束缚态Muon衰变进行了详细的分析，包括核反冲。简要讨论了对未来实验的影响。
Experimental searches for lepton-flavor-violating coherent muon-to-electron conversion in the field of a nucleus, have been proposed to reach the unprecedented sensitivity of 10^(-16) - 10^(-18) per stopped muon. At that level, they probe new interactions at effective-mass scales well beyond 1000 TeV. However, they must contend with background from ordinary bound muon decay. To better understand the background-spectrum shape and rate, we have carried out a detailed analysis of Coulombic-bound-state muon decay, including nuclear recoil. Implications for future experiments are briefly discussed.
