Periodic structure in nuclear matter.
The properties of nuclear matter are studied in the framework of quantum hadrodynamics. Assuming an o-meson field, periodic in space, a self-consistent set of equations is derived in the mean-field approximation for the description of nucleons interacting via U-meson and w-meson fields. Solutions of these self-consistent equations have been found: The baryon density is constant in space, howeve...
متن کاملStructure of the vacuum in nuclear matter: A nonperturbative approach
We compute the vacuum polarization correction to the binding energy of nuclear matter in the Walecka model using a nonperturbative approach. We first study such a contribution as arising from a ground-state structure with baryon-antibaryon condensates. This yields the same results as obtained through the relativistic Hartree approximation of summing tadpole diagrams for the baryon propagator. S...
متن کاملHadronization in Nuclear Matter
Nuclei are unique analyzers of the space-time development of jets at early stage. We argue that the gluon bremsstrahlung, rather than the color string, is the main mechanism of hadronization of highly virtual quarks produced in a hard interaction. It results in an energyand time-independent density of energy loss, like a color string, but steeply dependent on the quark virtuality. Effects of fo...
متن کاملDibaryons in Nuclear Matter
The possibility for occurrence of a Bose condensate of dibaryons in nuclear matter is investigated within the framework of the Walecka model in the mean-field approximation. Constraints for the ωand σ-meson coupling constants with dibaryons following from the requirement of stability of dibaryon matter against compression are derived and the effect of σand π-meson exchange current contributions...
متن کاملKaons in Nuclear Matter
The kaon energy in a nuclear medium and its dependence on kaonnucleon and nucleon-nucleon correlations is discussed. The transition from the Lenz potential at low densities to the Hartree potential at high densities can be calculated analytically by making a Wigner-Seitz cell approximation and employing a square well potential. As the Hartree potential is less attractive than the Lenz one, kaon...
