Perturbation theory for a systematic account of the bound-state motion
Alexander N. Kvinikhidze, Hagop Sazdjian, Boris Blankleider
We derive a perturbation theory (PT) for the Lorentz boost operator in the space of two-nucleon wave functions. The latter is expressed in terms of the nucleon-nucleon () poten…

Exact unified tetraquark equations
B. Blankleider, A. N. Kvinikhidze
Recently we formulated covariant equations describing the tetraquark in terms of an admixture of two-body states (diquark-antidiquark), (meson-meson), and three-body…
