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…
Unified triquark equations
A. N. Kvinikhidze, B. Blankleider
We derive covariant equations describing the three-quark bound state in terms of quark and diquark degrees of freedom. The equations are exact in the approximation where three-body…
New derivation of Time-Independent Perturbation Theory
A. N. Kvinikhidze, B. Blankleider
We propose a new derivation of Time-Independent Perturbation Theory (PT) that has a fundamental advantage over the usual derivations presented in textbooks on Quantum Mechanics (QM…
Unified tetraquark equations
A. N. Kvinikhidze, B. Blankleider
We derive covariant equations describing the tetraquark in terms of an admixture of two-body states (diquark-antidiquark), (meson-meson), and three-body-like states…
Comment on "-meson: Four-quark versus two-quark components and decay width in a Bethe-Salpeter approach"
B. Blankleider, A. N. Kvinikhidze
In a recent paper by N. Santowsky et al. [Phys. Rev. D 102, 056014 (2020)], covariant coupled equations were derived to describe a tetraquark in terms of a mix of four-quark states…
