Description
B-meson decays with ψ(2S) in the final state offer a way to study exotic hadrons with hidden charm alongside studies with J/ψ. This contribution reviews results from Belle, BaBar, CMS, and LHCb, from the first observation of the charged Z(4430) structure to recent amplitude analyses. The focus is on recent LHCb studies of B⁺ → ψ(2S)K⁺π⁺π⁻ and B⁺ → ψ(2S)K⁰ₛπ⁺ decays, which reveal new exotic structures and provide further information on the properties of Z(4430)⁺.
