    "abstract": "We study the symmetry energy in infinite nuclear matter employing a\nnon-relativistic Brueckner-Hartree-Fock approach and using various new\nnucleon-nucleon (NN) potentials, which fit np and pp scattering data very\naccurately. The potential models we employ are the recent versions of the\nNijmegen group, Nijm-I, Nijm-II and Reid93, the Argonne $V_{18}$ potential and\nthe CD-Bonn potential. All these potentials yield a symmetry energy which\nincreases with density, resolving a discrepancy that existed for older NN\npotentials. The origin of remaining differences is discussed.",
