英文摘要	The mass spectrum of hidden charm pentaquark states composed of two diquarks and an antiquark are calculated by use of an effective Hamiltonian which includes explicitly the spin, color, and flavor dependent interactions. The results show that the P-c(4312)(+) and P-c(4440)(+) states could be explained as hidden charm pentaquark states with isospin and spin-parity I J(P) = 1/2(3/2(-)), the P-c(4457)(+) state could be explained as a hidden charm pentaquark state with I J(P) = 1/2(5/2(-)), and the P-cs (4459)(+) state could be explained as a hidden charm pentaquark state with I J(P) = 0(1/2(-)) or 0(3/2(-)). Predications for the masses of other possible pentaquark states are also given, and the possible decay channels of these hidden charm pentaquark states are discussed.
