英文摘要: In the framework of one-pion-exchange (OPE) model, we study the hidden-charm and charm-strange molecular pentaquark systems composed of a heavy baryon (Sigma(c), Sigma(c)*) and a vector meson ((K) over bar*, (D) over bar*), where the S-D mixing effect is considered in our calculation. Our result shows that the Sigma(c)(D) over bar* molecular state with (I = 1/2, J(P) = 3/2(-)) and the Sigma(c)*(D) over bar* molecular state with (I = 1/2, J(P) = 5/2(-)) exist in the mass range of the observed P-c(4380) and P-c(4450), respectively. Moreover, we predict two other hidden-charm molecular pentaquarks with configurations Sigma(c)(D) over bar* (I = 3/2, J(P) =1/2(-)) and Sigma(c)*(D) over bar* (I = 3/2, J(P) = 1/2(-)) and two charm-strange molecular pentaquarks P-cs (3340) and P-cs (3400) corresponding to the Sigma c (K) over bar* configuration with (I = 1/2, J(P) = 3/2(-)) and the Sigma(c)*(K) over bar* configuration with (I = 1/2, J(P) = 5/2(-)), respectively. Additionally, we also predict some hidden-bottom Sigma B-(*)(b)* and B-c-like Sigma(c)*B*/Sigma((*))(b)(D) over bar& pentaquarks. (C) 2016 Elsevier B.V. All rights reserved.
