    "abstract": "The self-energy of the K^- meson in nuclear matter is calculated in a\nself-consistent microscopic approach, using a \\bar{K}N interaction obtained\nfrom the lowest-order meson-baryon chiral Lagrangian. The effective \\bar{K}N\ninteraction in the medium is derived by solving the coupled-channel\nBethe-Salpeter equation including Pauli blocking on the nucleons, mean-field\nbinding potentials for the baryons and the self-energy of the \\pi and \\bar{K}\nmesons. The incorporation of the self-consistent {\\bar K} self-energy in the\ndescription, in addition to the Pauli blocking effects, yields a weaker\nattractive in-medium {\\bar K}N interaction and a \\Lambda(1405) which dissolves\nfaster with increasing matter density, as a result of the {\\bar K} spectral\nfunction being spread out over a wide range of energies. These effects are\nfurther magnified when the intermediate pions are dressed.",
