| 英文摘要 | Very recently, two hidden-charmed resonances P-c(4380) and P-c(4450) consistent with pentaquark states were observed at the LHCb detector. The two Pcstates locate just below the (D) over bar Sigma(c)* and (D) over bar* Sigma(c) thresholds with mass of gapsabout 5 and 15MeV, respectively. Inspired by this fact we perform a dynamical investigation about the (D) over bar*Sigma(c)(2520) and (D) over bar* Sigma(c)(2455) interactions which are described by the meson exchanges. A bound state which carries spin-parity J(P) = 3/2(-) is produced from the (D) over bar Sigma(c*)(2520) interaction, which is consistent with the P-c(4380) observed at the LHCb detector. From the (D) over bar* Sigma(c)(2455) interaction, a bound state with 5/2(+) is produced, which can be related to the P-c(4450). The results suggest that the P-c(4380) and P-c(4450) are good candidates of (D) over bar* Sigma(c)*(2520) and (D) over bar*Sigma(c)(2455) molecular states, respectively. (C) 2016 The Author.
