Short range correlation in relativistic Hartree-Fock model for infinite nuclear matter

Abstract

We construct a new framework in the relativistic Hartree‐Fock approximation with the form factor and short range correlation (RHFU) to study the properties of nuclear matter. The unitary correlation operator method (UCOM) is used to treat the short range correlation. With this model, we can completely reproduce the equation of state of pure neutron matter in the Dirac Brueckner‐Hartree‐Fock theory with Bonn potential. We also discuss the symmetric nuclear matter with the RHFU model. The contribution of ρ meson is cut down largely by the effect of form factor of the size in the Bonn potential. The short range correlation has very important influence on the Fock energies of pion and ρ meson.
