Abstract
The possibility of describing the charged charmonium-like state Z+(4430) as the kinematical rescattering effect is examined. This approach makes it possible to avoid the introduction of exotic hadron states in the model, and one describes structures in the ψ(2S)π+ mass spectrum by the presence of the Ds(*)′ resonance in a hidden intermediate state. The resulting model predictions are compared with the results obtained by the LHCb Collaboration.
