| dc.description | The s- and p-wave contributions to the $\bar K N$ interaction in dense nuclear matter are obtained using a chiral unitary approach. We perform a self-consistent calculation of the $\bar K$ 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 $\bar K$ bound states could be observed. | |
