为什么三体物理学不能解决质子半径之谜

Why three-body physics do not solve the proton radius puzzle

Jean-Philippe Karr, Laurent Hilico

摘要:

研究了μ子氢谱实验[1]中弱束缚三体系统的可能参与,该实验可以解决当前质子半径测定之间的差异。使用具有复数坐标旋转的变分计算,表明最近被提出作为可能候选者的$pμe$离子在感兴趣的能量区域中没有共振态。QED能级位移包括唯象包括汤川势的三体库仑哈密顿对角化之前。它也表明,$ppμ$分子离子不能发挥任何作用,在观察线。

英文摘要:

The possible involvement of weakly bound three-body systems in the muonic hydrogen spectroscopy experiment [1], which could resolve the current discrepancy between determinations of the proton radius, is investigated. Using variational calculations with complex coordinate rotation, it is shown that the $pμe$ ion, which was recently proposed as a possible candidate [2], has no resonant states in the energy region of interest. QED level shifts are included phenomenologically by including a Yukawa potential in the three-body Coulomb Hamiltonian before diagonalization. It is also shown that the $ppμ$ molecular ion cannot play any role in the observed line.
