Hypernuclei in the quark-meson coupling model
Abstract
We present results of hypernuclei calculated in the latest quark-meson coupling (QMC) model, where the effect of the mean scalar field in-medium on the one-gluon exchange hyperfine interaction, is also included self-consistently. The extra repulsion associated with this increased hyperfine interaction in-medium completely changes the predictions for hypernuclei. Whereas in the earlier version of QMC they were bound by an amount similar to hypernuclei, they are unbound in the latest version of QMC, in qualitative agreement with the experimental absence of such states.
