    "abstract": "We extend the effective field theory approach which successfully describes\nordinary nuclei and nuclear matter to incorporate strangeness in nuclear\nstructure. Central object is a chiral effective Lagrangian involving the baryon\noctet, the Goldstone boson octet, the vector meson octet and a light scalar\nsinglet. According to the rules of effective field theory, we include all\ninteraction terms (up to a given order of truncation) that are consistent with\nthe underlying symmetries of QCD. We develop a mean-field approximation and\nstudy nuclear matter as a simple model for multi-strange systems. A D-type\nYukawa coupling between baryons and vector mesons leads to lambda-sigma^0\nflavor mixing in the nuclear medium. We study flavor oscillations in the\nnuclear matter ground state which are closely related to the phenomenon of\nneutrino oscillations.",
