  Antikaons in dense nuclear matter are studied using a chiral unitary approach
which incorporates the $s$- and p-waves of the $\bar K N$ interaction. We
include, in a self-consistent way, Pauli blocking effects, meson self-energies
modified by nuclear short-range correlations and baryon binding potentials. We
show that the on-shell factorization cannot be applied to evaluate the
in-medium corrections to p-wave amplitudes. We also obtain an attractive shift
for the $\Lambda$ and $\Sigma$ masses of -30 MeV at saturation density while
the $\Sigma^*$ width gets sensibly increased to about 80 MeV. The moderate
attraction developed by the antikaon does not support the existence of very
deep and narrow bound states.
