Amplitude analysis of B⁰→ηc(1S)K⁺π⁻ decays arxiv.org/abs/2509.03133 - The data are described with a model including only intermediate contributions from known K*⁰ resonances. Evidence for an exotic resonance in the ηcπ⁻ system, reported in a previous analysis of this decay channel, is not confirmed.
