Three-Loop Corrections to Lamb Shift in Muonium and Positronium

High Energy Physics - Phenomenology 2022-01-19 v2 Atomic Physics

Abstract

We calculate hard spin-independent three-loop radiative corrections to energy levels in muonium and positronium which are due to radiative insertions in two-photon exchange diagrams. These corrections could be relevant for the new generation of precise 1S2S1S-2S and 2S2P2S-2P measurements in muonium and positronium.
