论文摘要
$ \ bar {d}^{（*）}λ_c-\ bar {d}^{（*）}σ_c^{（*）} $的相互作用是在动态耦合 - 渠道方法的框架内研究的。在隐藏的魅力部门中，动态生成了一系列具有不同自旋和奇偶校验的结合状态和共振。在4.3至4.5 GEV的质量范围内发现了四个$ s $ - 波的绑定状态，靠近LHCB观察到的五夸克州。两个州的旋转奇偶校验为$ j^p = 1/2^ - $，另外两个具有$ j^p = 3/2^ - $。此外，预测具有不同自旋和奇偶校验的几种共振。
The interactions of $\bar{D}^{(*)} Λ_c - \bar{D}^{(*)}Σ_c^{(*)}$ are studied within the framework of a dynamical coupled-channel approach. A series of bound states and resonances with different spin and parity are dynamically generated in the hidden charm sector. Four $S$-wave bound states are found in the mass range of 4.3 to 4.5 GeV, close to the pentaquark states observed by LHCb. Two of the states have a spin parity of $J^P= 1/2^-$ and the other two have $J^P=3/2^-$. In addition, several resonances with different spin and parity in higher partial waves are predicted.
