dc.description.abstract	The s- and p-wave contributions to the K¯N interaction in dense nuclear matter are obtained using a chiral unitary approach. We perform a self-consistent calculation of the K¯ self-energy including Pauli blocking effects, meson self-energies modified by short-range correlations and baryon binding potentials. We find that the on-shell factorization cannot be applied to evaluate the in-medium corrections to p-wave amplitudes. Furthermore, the Λ and Σ develop a mass shift of -30 MeV at saturation density while the Σ∗ width increases to 80 MeV. We conclude that no deep and narrow K¯ bound states could be observed.
