Weak decays of heavy hadron molecules involving the f0(980)

TL;DR

This paper investigates the weak decays of certain heavy mesons involving the f0(980) resonance, assuming they are hadronic molecules, to provide predictions that can test this structural hypothesis in future experiments.

Contribution

It offers a novel analysis of heavy meson decays under the hadronic molecule assumption, enabling experimental tests of this structural interpretation.

Findings

Predictions for decay observables based on the hadronic molecule model

Potential to distinguish molecular structure through experimental measurements

Enhanced understanding of f0(980) involvement in heavy meson decays

Abstract

We study weak decays of the charm- and bottom-strange mesons Ds0*(2317), Ds1(2460), Bs0*(5725) and Bs1(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.
