    "abstract": "We present results of a self-consistent calculation for the kaon and antikaon\nspectral functions in cold nuclear matter, using as input the kaon-nucleon and\nantikaon-nucleon scattering amplitudes of the vacuum. We investigate the effect\nof in-medium pion dressing on the antikaon-nucleon scattering amplitudes and\nantikaon spectral function. We find the influence of pion dressing to be minor\non the antikaon spectral function and limited on the hyperon resonances causing\nonly a small additional broadening. An exception is the \\Sigma(1690). At\nnuclear saturation density an attractive mass shift of about 20 MeV and width\nof about 130 MeV is obtained. The kaon shows a repulsive mass increase of 36\nMeV and a small width of the quasiparticle peak at saturation density.",
