  text: Spin mixtures of degenerate fermions are a cornerstone of quantum many-body
    physics, enabling superfluidity, polarons, and rich spin dynamics through s-wave
    scattering resonances. Combining them with strong, long-range dipolar interactions
    provides highly flexible control schemes promising even more exotic quantum phases.
    Recently, microwave shielding gave access to spin-polarized degenerate samples
    of dipolar fermionic molecules, where tunable p-wave interactions were enabled
    by field-linked resonances available only by compromising the shielding (due to
    experimental limitations). Here, we study the scattering properties of a fermionic
    dipolar spin mixture and show that a universal s-wave resonance is readily accessible
    without compromising the shielding. We develop a universal description of the
    tunable s-wave interaction and weakly bound tetratomic states based on the microwave-field
    parameters. The s-wave resonance paves the way to stable, controllable and strongly-interacting
    dipolar spin mixtures of deeply degenerate fermions and supports favorable conditions
    to reach this regime via evaporative cooling.

  text: 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.
