论文摘要
在Fermion线和交换光子中，硬旋转非依赖性的三环辐射贡献对具有单环辐射插入的两光子交换图产生的正电子水平的贡献。这是对新一代精确$ 1S-2S $和$ 2S-2P $ sublesurions in Potitronium启发的所有订单$Mα^7 $的计算的下一步。
Hard spin-independent three-loop radiative contributions to energy levels in positronium generated by the two-photon-exchange diagrams with one-loop radiative insertions in the fermion lines and exchanged photons are calculated. This is a next step in calculations of all corrections of order $mα^7$ inspired by the new generation of precise $1S-2S$ and $2S-2P$ measurements in positronium.
