    "abstract": "We study the properties of the kappa meson in the nuclear medium, starting\nfrom a chiral unitary model of S-wave, I=1/2 K-pi scattering, which describes\nthe elastic K-pi phase shifts and generates a pole in the amplitude. Medium\neffects are considered by including pion and kaon selfenergies. We explore the\nchanges in the kappa pole position and in the K-pi scattering amplitude at\nfinite density, with two different models for the kaon selfenergy.",
