dc.description.abstractWe study the interaction between the muon and proton in muonic hydrogen induced by the effective exchange of axial vector, scalar, pseudoscalar and tensor mesons in the light-by-light scattering. The transition form factor meson is taken in the monopole form over each photon momentum squared which is usually used in the analysis of corresponding experimental date. Numerical contributions of meson interaction to fine and hyperfine structure are obtained.ru
