Hadron Contribution of Light-by-Light Scattering to Hyperfine Splitting in Muonium
The hadron light-by-light scattering contribution to the superfine splitting of the muonium ground state is calculated. The quasi-potential of muon and electron interaction is expressed in terms of the form factor of transition of two virtual photons to a meson. The contributions of pseudoscalar, pseudovector, scalar, and tensor mesons are considered.
