Widths of tetraquarks with open charm
S. M. Gerasyuta, V. I. Kochkin
In the framework of coupled-channel formalism the relativistic four-quark equations are found. The dynamical mixing of the meson-meson states with the four-quark states is consider…

Relativistic five-quark equations and a narrow N(1688) resonance
S. M. Gerasyuta, V. I. Kochkin
The relativistic five-quark equations are found in the framework of the dispersion relation technique. The five-quark amplitude for the N(1688) resonance including u-, d- quarks is…
