Investigation of logarithmic contributions in the electron-to-muon mass ratio to the shift of the S energy levels in the muonium atom
Tóm tắt
New logarithmic corrections in the mass ratio to the shift of the 1S and 2S energy levels in the muonium atom are calculated analytically. Corrections of this type that have been obtained so far are discussed and systematized.
