Abstract

We study weak decays of the charm- and bottom-strange mesons D_s0^*(2317), D_s1(2460), B_s0^*(5725) and B_s1(5778) with f₀(980) in the final state by assuming a hadronic molecule interpretation for their structures. Since in the proposed framework the initial and final states are occupied by hadronic molecules, the predictions for observables can provide a sensitive tool to further test the hadronic molecule structure in future experiments.
