We review the important role played by the chiral SU(3) symmetry in
predicting the properties of antikaons and hyperon resonances in cold nuclear
matter. Objects of crucial importance are the meson-baryon scattering
amplitudes obtained within the chiral coupled-channel effective field theory.
The formation of baryon resonances as implied by chiral coupled-channel
dynamics is discussed. Results for antikaon and hyperon-resonance spectral
functions are presented for isospin symmetric and asymmetric matter.Comment: invited talk presented by M.F.M.L. at the 18th Nishinomiya Yukawa
