Query: Weakly bound $H$ dibaryon from SU(3)-flavor-symmetric QCD   We present the first study of baryon-baryon interactions in the continuum
limit of lattice QCD, finding unexpectedly large lattice artifacts.
Specifically, we determine the binding energy of the $H$ dibaryon at a single
quark-mass point. The calculation is performed at six values of the lattice
spacing $a$, using O($a$)-improved Wilson fermions at the SU(3)-symmetric point
with $m_\pi=m_K\approx 420$ MeV. Energy levels are extracted by applying a
variational method to correlation matrices of bilocal two-baryon interpolating
operators computed using the distillation technique. Our analysis employs
L\"uscher's finite-volume quantization condition to determine the scattering
phase shifts from the spectrum and vice versa, both above and below the
two-baryon threshold. We perform global fits to the lattice spectra using
parametrizations of the phase shift, supplemented by terms describing
discretization effects, then extrapolate the lattice spacing to zero. The phase
shift and the binding energy determined from it are found to be strongly
affected by lattice artifacts. Our estimate of the binding energy in the
continuum limit of three-flavor QCD is $B_H^{\text{SU(3)}_{\rm
f}}=4.56\pm1.13_{\rm stat}\pm0.63_{\rm syst}$ MeV.
