Description
We present preliminary results on the $I=0$, $S=-2$ $H$ dibaryon in $N_f=2+1$ QCD. The calculation is performed with heavier-than-physical quarks ($m_\pi \approx 280$ MeV) on a single CLS ensemble. Correlation matrices are constructed using the distillation technique and the three relevant channels, $\Lambda\Lambda$, $N\Xi$, $\Sigma\Sigma$, are investigated to determine the interacting spectrum relevant for S-wave across multiple momentum frames. The scattering amplitude is investigated by solving the corresponding two-body quantization condition. These preliminary results are part of the ongoing efforts to determine the properties of hyperons and to establish whether a bound $H$ dibaryon exists down to physical quark masses.
