μ介子超精细分裂的三圈辐射反冲修正:带极化圈的图解

Three-Loop Radiative-Recoil Corrections to Hyperfine Splitting in Muonium: Diagrams with Polarization Loops

Michael I. Eides, Valery A. Shelyuto

摘要:

我们考虑三圈辐射反冲修正产生的超精细分裂与电子和μ子真空极化图的μ子。我们计算单对数和非对数的贡献的顺序$α^3(m/M)E_F$规范不变集的图表与电子和μ子极化插入电子和μ子的因素。结合新的贡献与我们的旧的结果,我们提出了完整的结果所产生的电子和μ子极化回路的图的所有三个回路的辐射反冲修正。

英文摘要:

We consider three-loop radiative-recoil corrections to hyperfine splitting in muonium generated by the diagrams with electron and muon vacuum polarizations. We calculate single-logarithmic and nonlogarithmic contributions of order $α^3(m/M)E_F$ generated by gauge invariant sets of diagrams with electron and muon polarization insertions in the electron and muon factors. Combining the new contributions with our older results we present complete result for all three-loop radiative-recoil corrections generated by the diagrams with electron and muon polarization loops.
