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.

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
