论文摘要
Muonic原子的激光光谱法最近已用于以前所未有的精度探测光核的性质。我们在类似氢的原子，核子结构量（形式，结构函数，极化能力）中引入核效应及其在Muonic氢（$μ$ H）的羔羊移位和高精细分裂（HFS）中的作用。提出了针对羔羊换档的更新理论预测和$μ$ H中的HFS。我们回顾了持续的努力挑战，以$μH$ H中的地面HFS及其对我们对核子旋转结构的理解的影响。为了缩小此搜索的范围，我们提出了一种新的理论预测，通过缩放利用辐射校正的氢测得的HFS获得。我们还总结了简单原子和分子系统光谱的最新发展，并强调了它们如何允许精确确定基本常数，结合状态QED测试和新的物理搜索。
Laser spectroscopy of muonic atoms has been recently used to probe properties of light nuclei with unprecedented precision. We introduce nuclear effects in hydrogen-like atoms, nucleon structure quantities (form factors, structure functions, polarizabilities) and their effects in the Lamb shift and hyperfine splitting (HFS) of muonic hydrogen ($μ$H). Updated theory predictions for the Lamb shift and HFS in $μ$H are presented. We review the challenges of the ongoing effort to measure the ground-state HFS in $μ$H and its impact on our understanding of the nucleon spin structure. To narrow down this search, we present a novel theory prediction obtained by scaling the measured HFS in hydrogen leveraging radiative corrections. We also summarize recent developments in the spectroscopy of simple atomic and molecular systems and emphasize how they allow for precise determinations of fundamental constants, bound-state QED tests and New Physics searches.
