Relativistic Mean Field Approach with Density and Momentum-Dependent Coupling Vertices

Abstract

We discuss alternative parametrizations of relativistic mean field models with density and momentum-dependent coupling vertices. This dependence has to be field-operator-valued and thus leads to additional re-arrangement terms in the self energies. We review that the static properties of nuclei are very well described by a density dependence alone. We further show that a dependence on derivatives of field operators leads to energy de-pendent self energies, and thus, in principle, to a description of the energy dependence of elastic scattering.
