N2 - The s- and p-wave contributions to the (K)[overline]N interaction in dense nuclear matter are obtained using a chiral unitary approach. We perform a self-consistent calculation of the (K) [overline] 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 ? and ? develop a mass shift of -30 MeV at saturation density while the ?* width increases to 80 MeV. We conclude that no deep and narrow (K)[overline] bound states could be observed.
