论文摘要
我们在无效的野外理论框架中通过近代到领先的顺序计算杜特隆的纵向结构函数。我们使用这些结果来计算Muonic氘中羔羊偏移的两光子极化能力的贡献，该氘可用于提取杜特隆的核电半径。我们介绍了相关过渡矩阵元素和纵向结构函数的分析表达式顺序，我们给出了对羔羊移位的相应贡献的数值结果。我们还讨论了相对论和其他高阶效应的影响。我们发现与以前的计算一致，并解释计算的准确性。
We calculate the longitudinal structure function of the deuteron up through next-to-next-to-leading order in the framework of pionless effective field theory. We use these results to compute the two-photon polarizability contribution to Lamb shift in muonic deuterium, which can be utilized to extract the nuclear charge radius of the deuteron. We present analytical expressions order-by-order for the relevant transition matrix elements and the longitudinal structure function, and we give numerical results for the corresponding contributions to the Lamb shift. We also discuss the impact of relativistic and other higher-order effects. We find agreement with previous calculations and explain the accuracy of our calculation.
