我们计算了双光子交换图中极化插入的辐射修正对介子和正电子能级的硬自旋无关的三环辐射修正。这些修正可能与新一代精确测量介子和正电子的1S-2S和2S-2P有关。
We calculate hard spin-independent three-loop radiative corrections to energy levels in muonium and positro-nium which are due to radiative corrections with polarization insertions in two-photon exchange diagrams. These corrections could be relevant for the new generation of precise 1S-2S and 2S-2P measurements in muonium and positronium.
