| We study the properties of the kappa meson in the nuclear medium, starting from a chiral unitary model of S-wave, I=1/2 Kpi scattering, which describes the elastic Kpi phase shifts and generates a pole in the amplitude. Medium effects are considered by including pion and kaon self-energies. We explore the changes in the kappa pole position and in the Kpi scattering amplitude at finite density, with two different models for the kaon self-energy. | |||
