| 英文摘要 | We investigate the observed pentaquark candidates P-c(4312), P-c(4440), and P-c(4457) from the latest LHCb measurement, as well as four possible spin partners in the (D) over bar(*)Sigma(c)* system predicted from the heavy quark spin symmetry with the hadronic molecule scenarios. Similar to the previous calculation on P-c(4380) and P-c(4450), the partial widths of all the allowed decay channels for these P-c states are estimated with the effective Lagrangian method. The cutoff dependence of our numerical results is also presented. Comparing with the experimental widths, our results show that P-c(4312), P-c(4440), and P-c(4457) can be described well with the spin-parity-1/2(-)-(D) over bar Sigma(c), 1/2(-)-(D) over bar*Sigma(c), and 3/2(-)-(D) over bar*Sigma(c), molecule pictures, respectively. |
