论文摘要
在这项工作中，我们将$λ_C（2910）^+$和$λ_C（2940）^+$视为常规$ UDC $ cORES，穿着$ d^*n $ channel。我们为$λ_C（2910）^+$和$λ_C（2940）^+$提供了可能的解释。在研究中，我们不仅考虑传统的Triquark Core和$ d^*n $ channel之间的效果，还考虑$ d^*n $ - $ d^*n $互动之间的效果。 $ J^p = 1/2^ - $的$λ_C$状态大于$ j^p = 3/2^ - $在此未取消图片中的质量，这与常规淬火夸克模型的预测截然不同。基于质谱，$λ_c（2940）^+$的自旋 - 比值更可能为$ 1/2^ - $，而$λ_C（2910）^+$ prefers $ 3/2^ - $。我们期待未来的实验可以通过更精确的实验数据测试我们的结果。
In this work, we treat $Λ_c(2910)^+$ and $Λ_c(2940)^+$ as the conventional $udc$ cores dressed with the $D^*N$ channel. We provide a possible interpretation to both $Λ_c(2910)^+$ and $Λ_c(2940)^+$ within the same framework. In the study, we consider not only the effects between the conventional triquark core and the $D^*N$ channel but also the $D^*N$-$D^*N$ interactions. The mass of $Λ_c$ state with $J^P=1/2^-$ is larger than that with $J^P=3/2^-$ in this unquenched picture, which is very different from the prediction of the conventional quenched quark model. Based on the mass spectrum, the spin-parity of $Λ_c(2940)^+$ is more likely to be $1/2^-$ while $Λ_c(2910)^+$ prefers $3/2^-$. We look forward to the future experiments can test our results with more precise experimental data.
