束缚于原子核的μ介子的Michel衰变谱

Michel decay spectrum for a muon bound to a nucleus

摘要:

在原子束缚态中衰变的μ介子的电子光谱由于它们与原子核的相互作用而被显著地改变。有点出乎意料的是,它的第一次测量,在加拿大实验室TRIUMF,与基本理论不同。我们表明,使用原子,核和高能物理学中开发的技术相结合,辐射校正消除了差异。除了解决这个突出的问题,我们更精确的预测是潜在的有用解释未来的高统计μ子实验,旨在寻找奇异的相互作用在$10^{-16}$的灵敏度。

英文摘要:

The spectrum of electrons from muons decaying in an atomic bound state is significantly modified by their interaction with the nucleus. Somewhat unexpectedly, its first measurement, at the Canadian laboratory TRIUMF, differed from basic theory. We show, using a combination of techniques developed in atomic, nuclear, and high-energy physics, that radiative corrections eliminate the discrepancy. In addition to solving that outstanding problem, our more precise predictions are potentially useful for interpreting future high-statistics muon experiments that aim to search for exotic interactions at $10^{-16}$ sensitivity.
