Effective hadron masses and couplings in nuclear matter and incompressibility
نویسنده
چکیده
The role of effective hadron masses and effective couplings in nuclear matter is studied using a generalized effective Lagrangian for σ-ω model. A simple relation among the effective masses, the effective couplings and the incompressibility K is derived. Using the relation, it is found that the effective repulsive and the effective attractive forces are almost canceled to each other at the normal density. Inversely, if this cancellation is almost complete, K should be 250∼350MeV.

متن کاملSaturation properties and incompressibility of nuclear matter: A consistent determination from nuclear masses.
Starting with a two-body effective nucleon-nucleon interaction, it is shown that the infinite nuclear matter model of atomic nuclei is more appropriate than the conventional Bethe-Weizsacker like mass formulae to extract saturation properties of nuclear matter from nuclear masses. In particular, the saturation density thus obtained agrees with that of electron scattering data and the Hartree-Fo...
متن کاملExtraction of nuclear matter properties from nuclear masses by a model of equation of state
The extraction of nuclear matter properties from measured nuclear masses is investigated in the energy density functional formalism of nuclei. It is shown that the volume energy a1 and the nuclear incompressibility K0 depend essentially on μnN + μpZ − 2EN , whereas the symmetry energy J and the density symmetry coefficient L as well as symmetry incompressibility Ks depend essentially on μn − μp...
متن کاملVariations of hadron masses and matter properties in dense nuclear matter.
Using a self-consistent quark model for nuclear matter we investigate variations of the masses of the non-strange vector mesons, the hyperons and the nucleon in dense nuclear matter (up to four times the normal nuclear density). We find that the changes in the hadron masses can be described in terms of the value of the scalar mean-field in matter. The model is then used to calculate the density...
متن کاملRelativistic Mean-Field Model with Momentum-Dependent Self-Energies
The conventional relativistic mean-field model with minimal meson-nucleon couplings is extended by introducing derivative meson-nucleon couplings. Combining this approach with a density dependence of the coupling vertices leads to an improved description of nuclear matter and atomic nuclei, especially of effective masses and the optical potential. Introduction and Theoretical Model The relativi...
