质子的半径:大小很重要

The Radius of the Proton: Size Does Matter

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

摘要:

Pohl等人[1]对μ子氢中2S_1/2^F=1到2P_3/2^F=2跃迁的测量和随后的分析得出的结论是,质子的均方根电荷半径与公认的(CODATA [2])值相差约4%,导致4.9 s.d.。差异我们调查的μ介子氢光谱相关的这种过渡使用束缚态QED与狄拉克波函数和评论的程度,导致上述结论的微扰理论分析可以证实。

英文摘要:

The measurement by Pohl et al. [1] of the 2S_1/2^F=1 to 2P_3/2^F=2 transition in muonic hydrogen and the subsequent analysis has led to a conclusion that the rms charge radius of the proton differs from the accepted (CODATA [2]) value by approximately 4%, leading to a 4.9 s.d. discrepancy. We investigate the muonic hydrogen spectrum relevant to this transition using bound-state QED with Dirac wave-functions and comment on the extent to which the perturbation-theory analysis which leads to the above conclusion can be confirmed.
