Charged charmonium-like Z+(4430) from rescattering in conventional B decays

In a previous paper we suggested an explanation for the peak designated as Z(4430)+ in the ψ′π+ mass spectrum, observed by Belle in B¯→ψ′π+K decays, as an effect of D¯⁎0D+→ψ′π+ rescattering in the decays B¯→Ds′−D, where the Ds′− is an as-yet unobserved radial excitation of the pseudoscalar ground st...
