  bibo_abstract:
  - We derive an analog of the Lellouch-Lüscher (LL) relation for few-body bosonic
    systems, linking few-body scattering loss rates to the energies and widths of
    the corresponding harmonically trapped few-body states. Three-body numerical simulations
    show that the LL relation applies across a broad range of interaction strengths
    and energies and allows the determination of scattering rates within a single
    partial wave. Our Letter establishes a robust theoretical framework for understanding
    the role of the finite-volume effect in few-body observables in optical lattice
    and tweezer experiments, enabling precise determination of multibody scattering
    rates.@eng
