Point-Coupling Models from Mesonic Hypermassive Limit and Mean-Field Approaches

O. Lourenço, M. Dutra, R. L. P. G. Amaral +1

In this work we show how nonlinear point-coupling models, described by a Lagrangian density that presents only terms up to fourth order in the fermion condensate $(\bar{\psi }\psi )$, are de…
