电子偶素兰姆位移的三圈修正:电子因子和极化

Three-Loop Corrections to Lamb Shift in Positronium: Electron Factor and Polarization

Michael I. Eides, Valery A. Shelyuto

摘要:

计算了在费米子线和交换光子中有单圈辐射插入的双光子交换图产生的与硬自旋无关的三圈辐射对正电子偶素能级的贡献。这是计算$mα^7$阶的所有修正的下一步,其灵感来自于新一代的精确的$1S-2S$和$2S-2P$在正电子素中的测量。

英文摘要:

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.
