Abstract: Mass and structure of $^{16}$O and $^{40}$Ca are deduced from the quantum chromodynamics (QCD),the fundamental theory of the strong interaction. We derive two-nucleon potentials in lattice QCD simulations by the HAL QCD method.Then we apply the potentials to the nuclei using the Brueckner-Hartree-Fock theory.We find that these two nuclei are bound and possess shell structures,for a heavy quark mass corresponding to a pseudo-scalar meson mass of 469 MeV (a nucleon mass of 1161 MeV).Obtained total binding energies, 35 MeV for $^{16}$O and 113 MeV for $^{40}$Ca,are rather smaller than the experimental data indeed,but it is due to the unrealistic quark mass in our lattice QCD simulations.
