Parametrization of the relativistic Dirac-Brueckner G matrix

Journal Article · · Phys. Rev. C; (United States)
; ; ; ;

A representation of the relativistic Brueckner G matrix by an effective interaction Lagrangian is proposed. This Lagrangian contains the four mesons sigma, ..omega.., ..pi.. (pseudovector), and rho (vector), with density-dependent coupling constants. It is shown that Dirac-Hartree-Fock calculations of nuclear matter using this effective interaction can reproduce well the results of the Dirac-Brueckner Hartree-Fock approach.
