    "abstract": "We investigate nuclear matter properties in the relativistic Brueckner\napproach. The in-medium on-shell T-matrix is represented covariantly by five\nLorentz invariant amplitudes from which we deduce directly the nucleon\nself-energy. To enforce correct Hartree-Fock results we develop a subtraction\nscheme which treats the bare nucleon-nucleon potential exactly in accordance to\nthe different types of meson exchanges. For the higher order correlations we\nemploy two different covariant representations in order to study the\nuncertainty inherent in the approach. The nuclear matter bulk properties are\nonly slightly sensitive on the explicit representation used. However, we obtain\nnew Coester lines for the various Bonn potentials which are shifted towards the\nempirical region of saturation.",
