Paired charmonium and bottomonium production in rare exclusive decays of Z boson
F. A. Martynenko, A. P. Martynenko, A. A. Skakun
The processes of paired charmonium and bottomonium production in Z-boson decays are investigated within the relativistic quark model. Various decay mechanisms are examined, and rel…
Improved calculation of the hyperfine structure of muonic helium
F. A. Martynenko, K. A. Seredina, A. P. Martynenko
Using perturbation theory for the fine-structure constant and the electron-to-muon mass ratio, we calculated new contributions to the hyperfine structure of the ground state of…
Rydberg states of muonic helium in quantum electrodynamics
A. V. Eskin, A. P. Martynenko, F. A. Martynenko +1
The variational method is used to study the energy levels of muonic helium with an electron in the ground state and a muon in an excited state with princip…
Few-particle lepton bound states in variational approach
A. V. Eskin, A. P. Martynenko, F. A. Martynenko +1
The energy levels of the ground states of the three-particle and four-particle bound states of leptons in quantum electrodynamics are calculated. For the calculation, the variation…
Weak Interaction Contribution to the Muonium Hyperfine Structure in the Standard Model
F. A. Martynenko, A. P. Martynenko, K. A. Seredina
The contribution of the weak interaction to the hyperfine splitting of the ground state of muonium is investigated. The amplitudes of the one- and two-quantum exchange determined b…
Heavy tetraquarks in the hyperspherical approach
F. A. Martynenko, A. V. Eskin, A. P. Martynenko
Within the quark model and hyperspherical method, the bound states of four heavy quarks and antiquarks (tetraquarks) are investigated. In hyperradial approximation, the Schroedinge…
