Improved calculation of the hyperfine structure of muonic helium
F. A. Martynenko, K. A. Seredina, A. P. Martynenko
Using perturbation theory for the fine-structure constant and the electron-to-muon mass ratio, we calculated new contributions to the hyperfine structure of the ground state of…

Weak Interaction Contribution to the Muonium Hyperfine Structure in the Standard Model
F. A. Martynenko, A. P. Martynenko, K. A. Seredina
The contribution of the weak interaction to the hyperfine splitting of the ground state of muonium is investigated. The amplitudes of the one- and two-quantum exchange determined b…
