英文摘要	The interactions of (D) over bar() Lambda(c) - (D) over bar() Sigma(c)(*) are studied within the framework of a dynamical coupled-channel approach. A series of bound states and resonances with different spin and parity are dynamically generated in the hidden charm sector. Four S-wave bound states are found in the mass range of 4.3-4.5 GeV, close to the pentaquark states observed by LHCb. Two of the states have a spin parity of J(P) = 1/2(-) and the other two have J(P) = 3/2(-). In addition, several resonances with different spin and parity in higher partial waves are predicted.
