论文摘要
我们基于具有标准的夸克夸克相互作用的组成夸克模型，研究了隐藏培养的五夸克，$ q \ bar q qqq $，可再现低能量的介子和巴里昂光谱。我们利用由短程相互作用的库仑样性质产生的重夸克之间的动态相关性。与文献和实验数据中的其他结果进行了详细的比较。如数据所示，我们的结果显示了开放口味和隐藏味的五体味的不同模式。讨论了关于Quarkonia结合到核的存在的进一步含义。
We study hidden-flavor pentaquarks, $Q\bar Q qqq$, based on a constituent quark-model with a standard quark-quark interaction that reproduces the low-energy meson and baryon spectra. We make use of dynamical correlations between the heavy quarks arising from the Coulomb-like nature of the short-range interaction. A detailed comparison is made with other results in the literature and with experimental data. Our results show a different pattern for open-flavor and hidden-flavor pentaquarks, as suggested by the data. Further implications about the existence of quarkonia bound to nuclei are discussed.
