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…

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…

Mass spectrum of heavy tetraquarks in variational approach

A. V. Eskin, A. P. Martynenko, F. A. Martynenko

Within the framework of the quark model and the variational method, the bound states of four heavy quarks (tetraquarks) are investigated. The basis variational wave functions are c…

Production of heavy quark bound states in rare exclusive decays of Higgs boson

F. A. Martynenko, A. P. Martynenko, A. V. Eskin

The processes of pair production of S- and P- wave charmonium, as well as the production of the tetraquark (cc \bar{c} \bar{c}) in the Higgs boson decays are investigated within th…
