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