Resonant states of muonic three-particle systems with lithium, helium and hydrogen nuclei
A. V. Eskin, V. I. Korobov, A. P. Martynenko +1
We study the energy spectrum of three-particle systems (He-p-μ), (He-d-μ), (Li-p-μ) and (Li-d-μ) on the basis of variational approach with exponential and Gaussian basis. Using the…

Hadronic light-by-light scattering contribution to 1S-2S transition in muonium
V. I. Korobov, F. A. Martynenko, A. P. Martynenko +1
We study hadronic light-by-light scattering contribution to the energy interval (1S-2S) in muonium. Various amplitudes of interaction of a muon and an electron are constructed, in…

Energy levels of mesonic helium in quantum electrodynamics
V. I. Korobov, A. V. Eskin, A. P. Martynenko +1
On the basis of variational method we study energy levels of pionic helium and kaonic helium with an electron in ground state and a meson in excited state wit…
