Abstract

The binding energies of a range of nuclei and hypernuclei with atomic number $A \leq 4$ and strangeness $| s | \leq 2$ , including the deuteron, dineutron, H-dibaryon, ${}^{3}{He}$ , ${}_{Λ}^{3}{He}$ , ${}^{4}{He}$ , ${}_{Λ}^{4}{He}$ , and ${}_{Λ Λ}^{4}{He}$ , are calculated in the limit of flavor-SU(3) symmetry at the physical strange-quark mass with quantum chromodynamics (without electromagnetic interactions). The nuclear states are extracted from lattice QCD calculations performed with $n_{f} = 3$ dynamical light quarks using an isotropic clover discretization of the quark action in three lattice volumes of spatial extent $L \sim 3.4 fm$ , 4.5 fm, and 6.7 fm, and with a single lattice spacing $b \sim 0.145 fm$ .
