论文摘要
将计算技术开发到五倍的重型载体上，我们通过QCD Sum规则方法方法对新型完全重量的$ qQQQ \ bar {q} $ pentaquark state进行研究，该方法是基于QCD基本理论而牢固地基于QCD的。从数值上讲，完全重量的五夸克状态的质量为$ 7.41^{+0.27} _ { - 0.31}〜\ mbox {gev} $ for $ cccc \ bar {c} $ $ bbbb \ bar {b} $。在实验中，可以在$ω_{qqq}η_{q} $不变质量谱搜索这些预测的全五个五夸克状态。
Developing the calculation techniques to fivefold heavy hadrons, we perform the study of novel fully-heavy $QQQQ\bar{Q}$ pentaquark states by the QCD sum rule approach that is firmly based on the QCD basic theory. Numerically, masses of fully-heavy pentaquark states are calculated to be $7.41^{+0.27}_{-0.31}~\mbox{GeV}$ for $cccc\bar{c}$ and $21.60^{+0.73}_{-0.22}~\mbox{GeV}$ for $bbbb\bar{b}$, respectively. In experiment, these predicted all-heavy pentaquark states could be searched for in the $Ω_{QQQ}η_{Q}$ invariant mass spectrum.
