In this work, we systematically investigate the mass spectra of fully-heavy hexaquarks within a constituent quark model by including the color Coulomb potential, linear confining potential, and spin-spin interactions. Our results show that all of the fully-heavy hexaquarks lie above the corresponding baryon-baryon thresholds, and thus no stable compact one exists. These states may subsist as resonances and decay into two fully-heavy baryons easily through the fall-apart mechanism, which can be searched in future experiments.

成分夸克模型中的全重六夸克

在这项工作中，我们通过包括颜色库仑势、线性限制势和自旋-自旋相互作用系统地研究了成分夸克模型中全重六夸克的质谱。我们的结果表明，所有的全重六夸克都位于相应的重子-重子阈值之上，因此不存在稳定的致密物质。这些状态可能以共振的形式存在，并通过分崩离析机制很容易地衰变为两个完全重的重子，这可以在未来的实验中进行搜索。
