Exotic states with QQQ-'Q- configuration

In the framework of a non-relativistic quark model, we have calculated the masses of the QQQ'Q' (Q = c, b, s and Q' = c, b, s) tetraquark states. Using the linear and quadratic confinement potentials inside a Cornell-type potential along with all possible spin and color configurations, the Schrodinger equation masses of these tetraquark states have been calculated. Based on our numerical analysis, linear confinement and quadratic confinement produce acceptable results. Models that use linear confinement estimate charmonium-like tetraquark mass close to experimental data, as well as bottomonium-like tetraquark mass below the threshold of their meson-meson channels .

Automated summary

In the framework of a non-relativistic quark model, the masses of the QQQ'Q' tetraquark states (where Q = c, b, s and Q' = c, b, s) were calculated. The Schrödinger equation masses of these tetraquark states were obtained using linear and quadratic confinement potentials inside a Cornell-type potential, considering all possible spin and color configurations. The analysis showed that both linear and quadratic confinement yielded reasonable results. Models using linear confinement estimated charmonium-like tetraquark mass close to experimental data, and bottomonium-like tetraquark mass below the meson-meson channels threshold.
