Two-Loop Polarization Contributions to Radiative-Recoil Corrections to Hyperfine Splitting in Muonium

Michael I. Eides, Howard Grotch, Valery A. Shelyuto

We calculate radiative-recoil corrections of order ${\alpha }^2(Z\alpha )(m/M)E_F$ to hyperfine splitting in muonium generated by the diagrams with electron and muon polarization loops. These co…
