μ⁺μ⁻谱的真空极化修正

Vacuum polarization corrections to $μ^+μ^-$ spectrum

Wayne W. Repko

AI总结:

本文基于正电子素高阶势计算真μ子素n=1、n=2能级,系统纳入电子真空极化、高阶微扰及多光子湮灭的α⁶阶修正,并给出基态超精细劈裂。

摘要:

从先前导出的、能正确描述正电子素到α⁵阶的势出发,并补充已知的α⁶阶贡献,计算了μ⁺μ⁻原子(真μ子素)n=1和n=2束缚态的能级。计算了真μ子素能级上所有电子真空极化修正至α⁶阶。还包含了势中所有α⁴和α⁵项的二阶微扰贡献。在基态(1³S₁-1¹S₀)超精细劈裂的计算中,纳入了来自双光子和三光子湮灭过程的额外α⁶阶贡献。

英文摘要:

The energy levels of the $n=1$ and $n=2$ bound states of the $μ^+μ^-$ atom (true muonium) are calculated starting from a previously derived potential that correctly describes positronium to order $α^5$ supplemented by the known $α^6$ contributions. All electron vacuum polarization corrections on the true muonium levels are computed to order $α^6$ order. The second order perturbative contributions from all of the $α^4$ and $α^5$ terms in the potential are also included. Additional order $α^6$ contributions from the two photon and three photon annihilation processes are included in the evaluation of the ground state ($1^3S_1-1^1S_0$) hyperfine splitting.
