    "abstract": "A new chiral SU(3) Lagrangian is proposed to describe the properties of kaons\nand antikaons in the nuclear medium, the ground state of dense matter and the\nkaon-nuclear interactions consistently.\n  The saturation properties of nuclear matter are reproduced as well as the\nresults of the Dirac-Br\\\"{u}ckner theory. Our numerical results show that the\nkaon effective mass might be changed only moderately in the nuclear medium due\nto the highly non-linear density effects. After taking into account the\ncoupling between the omega meson and the kaon, we obtain similar results for\nthe effective kaon and antikaon energies as calculated in the\none-boson-exchange model while in our model the parameters of the kaon-nuclear\ninteractions are constrained by the SU(3) chiral symmetry.",
