Relativistic mean-field interaction with density-dependent meson-nucleon vertices based on microscopical calculations
Although ab initio calculations of relativistic Brueckner theory lead to large scalar isovector fields in nuclear matter, at present, successful versions of covariant density functional theory neglect the interactions in this channel. A new high-precision density functional DD-ME$\ensuremath{\delta}$ is presented which includes four mesons, $\ensuremath{\sigma}$, $\ensuremath{\omega}$, $\ensuremath{\delta}$, and $\ensuremath{\rho}$, with …
