摘要

在单一-介子交换模型框架下,我们系统地对 charm 量子比特与轻子之间的 P 轨道相互作用进行耦合通道分析,涉及的通道包括 ΞcN\Xi_cN, ΛcΣ\Lambda_c\Sigma, ΞcN\Xi_c^{\prime}N, ΣcΛ\Sigma_c\Lambda, ΞcN\Xi_c^*N, ΣcΛ\Sigma_c^*\Lambda, ΣcΣ\Sigma_c\Sigma, 和 ΣcΣ\Sigma_c^*\Sigma。我们的结果可以预测几种可能的分子候选者,如 I(JP)=0(1)I(J^P)=0(1^-)ΞcN\Xi_c^{\prime}N 分子,0(0,1,2)0(0^-, 1^-, 2^-)ΞcN\Xi_c^{*}N 分子,0(1)0(1^-)1(1)1(1^-)ΣcΣ\Sigma_c\Sigma 分子,0(0,1,2)0(0^-, 1^-, 2^-)1(2)1(2^-)ΣcΣ\Sigma_c^*\Sigma 分子。Furthermore, the coupled channel effects significantly influence the formation of the ΣcΣ\Sigma_c\Sigma molecule with 1(1)1(1^-)。Furthermore, we analyze the phase shifts for these coupled channel systems. Our analysis not only confirms the existence of the predicted molecules but also identifies potential resonant dibaryons, including a ΣcΣ\Sigma_c\Sigma shape-type resonance with 1(1)1(1^-), a ΣcΣ\Sigma_c^*\Sigma shape-type resonance with 1(0)1(0^-), a ΛcΣ/ΣcΣ\Lambda_c\Sigma/\Sigma_c\Sigma coupled Feshbach-type resonance with 1(1)1(1^-), and ΛcΣ/ΣcΣ\Lambda_c\Sigma/\Sigma_c^*\Sigma coupled Feshbach-type resonances with 1(0,2)1(0^-, 2^-)
