Description
A new version of the quark-meson coupling model, in which the effect of gluon and pion exchanges is included self-consistently, is applied to hyperons in a nuclear medium. The hyperfine interaction due to the gluon exchange plays an important role in the in-medium baryon spectra, while the pion-cloud effect is relatively small. At the quark mean-field level, the Λ feels more attractive force than the Σ or Ξ in matter. (author)
