    "abstract": "Using a relativistic Dirac-Brueckner analysis the pion contribution to the\nground state energy of nuclear matter is studied. Evidence is presented that\nthe role of the tensor force in the saturation mechanism is substantially\nreduced compared to its dominant role in a usual non-relativistic treatment.\nThe reduction of the pion contribution in nuclear matter is due to many-body\neffects present in a relativistic treatment. In particular, we show that the\ndamping of OPEP is actually due to the decrease of $M^*/M$ with increasing\ndensity.",
