According to recent research from the United States, "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 alpha(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 these corrections with the older results, we obtain total contribution to hyperfine splitting generated by all diagrams with electron and muon polarization loops. The calculation of this contribution completes an important stage ...
