摘 要:In the framework of a non-relativistic quark model, we have calculated the masses of the QQ■(Q = c, b, s and ■=■,■,■) tetraquark states. Using the linear and quadratic confinement potentials inside a Cornell-type potential along with all possible spin and color configurations, the Schr?dinger equation masses of these tetraquark states have been *** 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.
