摘要：
Within the framework of three-channel Ross-Shaw effective range theory, we derive the constraints among different parameters of the theory in the case of a narrow resonance close to the threshold of the third channel, which is relevant for the resonancelike structure Z(c) (3900). The usage of these constraint relations, together with the multichannel Luscher formula in lattice QCD calculations are also discussed and the strategies are outlined.
