Light nuclei and hypernuclei from quantum chromodynamics in the limit of SU(3) flavor symmetry

The binding energies of a range of nuclei and hypernuclei with atomic number A≤4 and strangeness |s|≤2, including the deuteron, dineutron, H-dibaryon, ³He, _Λ³He, ⁴He, _Λ⁴He, and _ΛΛ⁴He, 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 nf=3 dynamical light quarks using an isotropic clover discretization of the quark action in three lattice volumes of spatial extent L~3.4 fm, 4.5 fm, and 6.7 fm, and with a single lattice spacing b~0.145 fm.
