论文摘要
我们合并了分散性关系方法和从头算法，以计算核结构校正到穆尼克申氘的羔羊转移。我们在手性有效野外理论中计算杜特隆响应函数和相应的不确定性，直到近代到接头到领先顺序，并将我们的结果与选定的电磁数据进行比较以测试该理论的有效性。然后，我们为分散理论的形式主义提供了在各种运动学上计算出的响应函数，并表明与在分散分析中使用可用的实验数据相比，获得了提高的精度。这打开了将这种混合方法应用于其他轻型原子的可能性，并通过从头开始理论补充了实验数据，以使数据稀缺或难以测量，目的是减少核结构效应原子镜头的不确定性的目的。
We merge the dispersive relation approach and the ab initio method to compute nuclear structure corrections to the Lamb shift in muonic deuterium. We calculate the deuteron response functions and corresponding uncertainties up to next-to-next-to-next-to-leading order in chiral effective field theory and compare our results to selected electromagnetic data to test the validity of the theory. We then feed response functions calculated over a wide range of kinematics to the dispersion-theory formalism and show that an improved accuracy is obtained compared to that with the use of available experimental data in the dispersive analysis. This opens up the possibility of applying this hybrid method to other light muonic atoms and supplementing experimental data with ab initio theory for kinematics where data are scarce or difficult to measure with the goal of reducing uncertainties in estimates of nuclear structure effects in atomic spectroscopy.
