Relativistic Hartree-Bogoliubov Approach for Nuclear Matter with Non-Linear Coupling Terms
نویسنده
چکیده
We investigate the pairing property of nuclear matter with Relativistic Hartree-Bogoliubov(RHB) approach. Recently, the RHB approach has been widely applied to nuclear matter and finite nuclei. We have extended the RHB approach to be able to include non-linear coupling terms of mesons. In this paper we apply it to nuclear matter and observe the effect of non-linear terms on pairing gaps. 21.60.-n, 21.65.+f Typeset using REVTEX e-mail: [email protected] e-mail: [email protected] e-mail: [email protected] 1

Nuclear Matter Properties in Derivative Coupling Models Beyond Mean-Field Approximation
The structure of in nite nuclear matter is studied with two of the Zimanyi Moszkowski (ZM) models in the framework of a relativistic approximation which takes into account Hartree terms and beyond and is compared with the results which come out of the relativistic Hartree Fock approach in the linear Walecka model. The simple treatment applied to these models can be used in substitution to the m...

متن کاملThe relativistic G-matrix approach and applications
The Dirac-Brueckner approach to the nuclear many-body problem is described. A family of relativistic mesonexchange potentials is used which apply the pseudovector coupling for the interaction of pseudoscalar mesons ( , ) with nucleons. These potentials describe low-energy two-nucleon scattering and the deuteron data accurately. Using these potentials, the properties of nuclear matter are calcul...
متن کاملPolarization Effects in Relativistic Nuclear Pairing
In the present work we discuss the effects of the medium polarization on the nuclear pairing, in the context of the relativistic Hartree-Fock-Bogoliubov (HFB) approximation. The medium polarization effects on the scalar and vector masses, as well on the pairing, as a function of Fermi momentum, are shown for several values of the coupling constants scaled by a parameter x. We find have obtained...
متن کاملVacuum Polarization Effects in Relativistic Nuclear Pairing
In the present work we discuss the contribution of the vacuum polarization on the nuclear pairing, in the context of the relativistic Hartree-Fock-Bogoliubov (HFB) approximation. The polarization effects on the pairing, as a function of Fermi momentum, is shown with the scalar and vector meson-nucleon coupling constants scaled by a parameter x. We have obtained that the nuclear pairing is affec...
