摘要

在无轴有效场论的框架下,通过次-次-先的顺序计算了氘核的纵向结构函数。我们利用这些结果计算了双光子极化率对介子氘兰姆位移的贡献,从而可以提取氘核的核电荷半径。我们给出了相关转移矩阵元素和纵向结构函数的逐级解析表达式,并给出了相应的Lamb位移贡献的数值结果。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,并解释了我们计算的准确性。

Pionless effective field theory evaluation of nuclear polarizability in muonic deuterium
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.
