For the purpose, we scan the properties of the matter at various saturation densities imposing constraint such as the vacuum value of the pion decay constant $f_{\\pi} \\approx 131 ~MeV$. With a simple approach, the bound on the mass of the scalar meson is calculated and found in the range $m_{\\sigma} = 546 \\pm 10 MeV$. Further, the present analysis show that nuclear matter favor high nucleon effective mass and dominant repulsive forces at high density, the insight and the implications of which are discussed.", "revisions": [ { "version": "v1", "updated": "2009-05-29T10:59:02.000Z" } ], "analyses": { "subjects": [ "21.65.-f", "13.75.Cs", "97.60.Jd", "21.30.Fe" ], "keywords": [ "chiral dynamics", "nuclear matter favor high nucleon", "favor high nucleon effective mass", "saturation densities imposing constraint", "light scalar meson" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 821670, "adsabs": "2009arXiv0905.4827J" } } }
