Description
Using perturbation theory for the fine-structure constant α and the electron-to-
muon mass ratio, we calculate new contributions to the hyperfine structure of the
ground state of the muon-electron helium atom. Compared to our previous results,
we incorporated new corrections in the second order of perturbation theory. This
calculation reduces the discrepancy between the theoretical value and the new ex-
perimental hyperfine structure measurement.
