Point-coupling Models from Mesonic Hypermassive Limit and Mean-field Approaches
In this work, we show how nonlinear point-coupling models, described by a Lagrangian density containing only terms up to fourth order in the fermion condensate ([bar over ψ]ψ), are derived from a modified meson-exchange nonlinear Walecka model. We present two methods of derivation, namely the hyperm...
