The charged Zc states from rescattering in conventional B decays

In this paper we discuss a possible interpretation of the charged charmonium-like states observed in B decays as a rescattering effect. This approach allows to avoid introduction of exotic hadrons into the theory, while explains the unusual peaking structures 4observed recently in three body B decays. In particular, the peaks in the ψ(2S)π+ mass spectrum are ascribed to the rescattering process with kinematics governed by the presence of conventional radial excitations, the Ds(*)' resonances, in the hidden intermediate state. Our predictions are compared to the LHCb results.
