Self-energy O(alpha^2) correction to the positronium decay rate
R. N. Faustov, A. P. Martynenko
Self-energy corrections of order O(alpha^2) to the parapositronium and orthopositronium decay rates are calculated. Numerical values of the corresponding coefficients are B_p=-3.74…

Corrections of order (Zα)^6 m^2_e/m_μin the muonium fine structure, induced by three photon exchange diagrams
R. N. Faustov, A. P. Martynenko
In the framework of the quasipotential method we calculate the contributions of the kind α^6\lnα, alpha^6 of three-photon exchange diagrams to the energy spectrum of muonium $n^3S_…
