    "abstract": "The properties of asymmetric nuclear matter have been investigated in a\nrelativistic Dirac-Brueckner-Hartree-Fock framework using the Bonn A potential.\nThe components of the self-energies are extracted by projecting on Lorentz\ninvariant amplitudes. Furthermore, the optimal representation scheme for the\n$T$ matrix, the subtracted $T$ matrix representation, is applied and the\nresults are compared to those of other representation schemes. Of course, in\nthe limit of symmetric nuclear matter our results agree with those found in\nliterature. The binding energy $E_b$ fulfills the quadratic dependence on the\nasymmetry parameter and the symmetry energy is 34 MeV at saturation density.\nFurthermore, a neutron-proton effective mass splitting of $m_n^* \u003c m_p^*$ is\nfound. In addition, results are given for the mean-field effective coupling\nconstants.",
