Abstract: | We consider three-loop radiative recoil corrections to hyperfine splitting in muonium due to insertions of the one-loop polarization
operator in the electron factor. The contribution generated by electron polarization insertions is a cubic polynomial in the
large logarithm of the electron—muon mass ratio. The leading logarithm cubed and logarithm squared terms are well known for
some time. We calculate all single-logarithmic and nonlogarithmic radiative recoil corrections of the order α3
(m/M)EF generated by diagrams with the electron and muon polarization insertions. |
