Description
Within the framework of the quark model and the hyperspherical coordinate method, we study the bound states of four heavy quarks (tetraquarks). In the hypercentral approximation, the Schrödinger equation is reduced to a one-dimensional equation after averaging over the hyperspherical angles. An analytical solution to this equation was obtained using the variational method, along with a numerical solution. The hyperfine structure of the spectrum was calculated. To improve the accuracy of the calculations, corrections to the energy levels from the Breit Hamiltonian were taken into account.
