Abstract
In the framework of a nonrelativistic chiral quark model, we continue to study the mass spectra of the fully-heavy and tetraquarks. In the present calculations, two structures, meson-meson [][] and diquark-antidiquark [][] ( = or ), and their mixing, along with all possible color, spin configurations are considered. The calculations suggest that no bound state can be formed for and systems. However, resonances are possible because of the color structure. Several resonances are predicted and their stabilities are checked using the real scaling method.
