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 princi…
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…
Production of dileptonic bound states in the Higgs boson decay
F. A. Martynenko, A. P. Martynenko, A. V. Eskin
The production of single and paired lepton bound states in the decay of the Higgs boson has been studied. We explore different decay mechanisms that contribute significantly to the…
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…
Production of heavy tetraquarks in rare exclusive decays of the Higgs boson
F. A. Martynenko, A. V. Eskin, A. P. Martynenko
The relativistic quark model is used to study the processes of heavy tetraquark production in the Higgs boson decay. We consider quark-gluon, ZZ-boson, and qua…
