The $H$ dibaryon from lattice QCD with SU(3) flavor symmetry

Abstract

We show recent results from the Mainz group using $N_f=2+1$ CLS ensembles generated at the $SU(3)$ symmetric point. Temporal correlation functions using two-baryon interpolating operators are calculated with the distillation method. In addition to the spin-0 operators relevant for studying the $H$ dibaryon, we added spin-1 operators to our basis, thereby extending our results to other flavor sectors. These preliminary results show a finite-volume energy below the $\Lambda \Lambda$ threshold. Further calculations are necessary to establish whether the $H$ dibaryon is bound at the physical point.
