论文摘要
在一类模型中，在标量粒子交换中主要引起了Lepton风味的侵蚀，我们将$μ\ \ $ \ \ $转换率在几个核中估计。我们在手性有效理论中的单核相互作用和两个核的相互作用中包括近代领导顺序（NLO）术语，从而纠正了先前文献中一些不正确的结果。我们为转换率提供了不确定性预算，我们发现NLO贡献会影响$ 10 \％$的幅度，这可能大于领先顺序耦合的不确定性，而奇怪和非差异核子Sigma项主导。我们通过将各种实验搜索的结果（例如在多个目标核中的$μ\ to e $ conversion量）结合到将来测试HIGGS介导的CLFV的含义，并将其含义。
Within a class of models in which lepton flavor violation is induced dominantly by scalar particle exchanges, we estimate the $μ\to e$ conversion rate in several nuclei. We include next-to-leading order (NLO) terms in the one- and two-nucleon interactions in chiral effective theory, rectifying some incorrect results in the previous literature. We provide an uncertainty budget for the conversion rates and we find that NLO contributions affect the amplitudes at the level of $10\%$, which could be larger than the uncertainty on the leading order couplings, dominated by the strange and non-strange nucleon sigma terms. We study the implications of our results for testing Higgs-mediated CLFV in the future by combining results from various experimental searches, such as $μ\to e$ conversion in multiple target nuclei and $μ\to e γ$.
