Fock exchange terms in nonlinear quantum hadrodynamics - art. no. 035202

We propose a method to introduce Fock term contributions in relativistic mo dels of fermions coupled to mesons, including self-interactions for the mes onic fields. We show that effects on equilibrium properties and on the dyna mical response of the fermionic system can be consistently accounted for. S ome implications on equilibrium properties of asymmetric nuclear matter are discussed. In particular an indication is emerging for a reduced contribut ion of charged mesons to the symmetry term of the nuclear equation of state around normal density.
