反对核极化作为μ子原子精细结构异常来源的证据

Evidence against nuclear polarization as source of fine-structure anomalies in muonic atoms

摘要:

通过考虑μ子$^{90}\mathrm{Zr}$、$^{120}\mathrm{Sn}$和$^{208}\mathrm{Pb}$中的$Δ2p$分裂以及μ子$^{208}\mathrm{Pb}$中的$Δ3p$分裂,重新讨论了μ子原子中精细结构异常的一个长期存在的问题.国家的最先进的技术,从核和原子物理学汇集在一起,以执行最全面的核极化能量变化的计算日期。除了μ子$^{208}\mathrm{Pb}$的更微妙的情况下,结果表明,占主导地位的计算不确定性比理论和实验之间的持续差异小得多。我们的结论是,解决的异常很可能植根于改进的QED校正,甚至其他一些以前无法解释的贡献。

英文摘要:

A long-standing problem of fine-structure anomalies in muonic atoms is revisited by considering the $Δ2p$ splitting in muonic $^{90}\mathrm{Zr}$, $^{120}\mathrm{Sn}$ and $^{208}\mathrm{Pb}$ and the $Δ3p$ splitting in muonic $^{208}\mathrm{Pb}$. State-of-the-art techniques from both nuclear and atomic physics are brought together in order to perform the most comprehensive to date calculations of nuclear-polarization energy shifts. Barring the more subtle case of muonic $^{208}\mathrm{Pb}$, the results suggest that the dominant calculation uncertainty is much smaller than the persisting discrepancies between theory and experiment. We conclude that the resolution to the anomalies is likely to be rooted in refined QED corrections or even some other previously unaccounted-for contributions.
