μ子氢谱的非微扰相对论计算

Non-Perturbative Relativistic Calculation of the Muonic Hydrogen Spectrum

J. D. Carroll, A. W. Thomas, J. Rafelski, G. A. Miller

摘要:

通过精确的、非微扰的数值解,考虑了有限尺寸的库仑力和真空极化,研究了μ子氢2 P ^{F=2}_{3/2}到2S^{F=1}_{1/2}的跃迁.结果与早期的微扰计算(主要)Borie,Martynenko,和Pachucki;和实验结果最近提出的Pohl等人,其中这种比较被解释为需要从电子散射和电子氢分析中获得的质子电荷半径进行修改。我们发现微扰和非微扰计算之间没有显着的差异,并提出我们的结果作为微扰方法的确认。

英文摘要:

We investigate the muonic hydrogen 2P^{F=2}_{3/2} to 2S^{F=1}_{1/2} transition through a precise, non-perturbative numerical solution of the Dirac equation including the finite-size Coulomb force and finite size vacuum polarization. The results are compared with earlier perturbative calculations of (primarily) Borie, Martynenko, and Pachucki; and experimental results recently presented by Pohl et al., in which this very comparison is interpreted as requiring a modification of the proton charge radius from that obtained in electron scattering and electronic hydrogen analyses. We find no significant discrepancy between the perturbative and non-perturbative calculations, and present our results as confirmation of the perturbative methods.
