Query: S-wave scattering of strangeness -3 baryons   We explore the interactions of two strangeness -3 baryons in multiple spin
channels with lattice QCD. This system provides an ideal laboratory for
exploring the interactions of multi-baryon systems with minimal dependence on
light quark masses. Model calculations of the two-$\Omega^-$ system in two
previous works have obtained conflicting results, which can be resolved by
lattice QCD. The lattice calculations are performed using two different volumes
with $L\sim2.5$ and 3.9 fm on anisotropic clover lattices at $m_\pi \sim 390$
MeV with a lattice spacing of $a_s \sim 0.123$ fm in the spatial direction and
$a_t\sim{a}_s/3.5$ in the temporal direction. Using multiple interpolating
operators from a non-displaced source, we present scattering information for
two ground state $\Omega^-$ baryons in both the S=0 and S=2 channels. For S=0,
$k\cot\delta$ is extracted at two volumes, which lead to an extrapolated
scattering length of $a^{\Omega\Omega}_{S=0}=0.16 \pm 0.22 \ \text{fm}$,
indicating a weakly repulsive interaction. Additionally, for S=2, two separate
highly repulsive states are observed. We also present results on the
interactions of the excited strangeness -3, spin-1/2 states with the ground
spin-3/2 states for the spin-1 and spin-2 channels. Results for these
interactions are consistent with attractive behavior.
