论文摘要
受观察到的$ x（2900）$的启发，我们以$ qQQQ \ bar {q} $（$ q = c，b $; $ q = n，s $; $ n = u，d $）配置在色彩磁相互作用模型的框架中配置。我们对它们的稳定性和衰减行为进行了详细的分析。我们的结果表明，可能存在狭窄的状态甚至稳定的状态。我们希望本研究能够激发实验主义者对寻找这种异国情调的五角星州的兴趣。
Inspired by the observed $X(2900)$, we study systematically the mass spectra of the ground pentaquark states with the $qqqq\bar{Q}$ ($Q=c,b$; $q=n,s$; $n=u,d$) configuration in the framework of the Chromomagnetic Interaction model. We present a detailed analysis of their stabilities and decay behaviors. Our results indicate that there may exist narrow states or even stable states. We hope that the present study may inspire experimentalist's interest in searching for such a type of the exotic pentaquark state.
