4 Θ + hypernuclei in relativistic mean field model
We have investigated the properties of Θ + in nuclei within the framework of relativistic mean field. The coupling constants are educed with quark meson coupling model. There is strong attractive interaction for Θ +-nucleus and Θ + can be bind in nuclei. The depth of optical potential for Θ + in nuclear matter is estimated.
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...
متن کاملSuperdeformations in Relativistic and Non-Relativistic Mean Field Theories
The applications of the extensions of relativistic mean field (RMF) theory to the rotating frame, such as cranked relativistic mean field (CRMF) theory and cranked relativistic Hartree-Bogoliubov (CRHB) theory, for the description of superdeformed bands in the A ∼ 60, 140 − 150 and 190 mass regions are overviewed and compared briefly with the results obtained in non-relativistic mean field theo...
متن کاملRelativistic mean field model for entrainment in general relativistic superfluid neutron stars
General relativistic superfluid neutron stars have a significantly more intricate dynamics than their ordinary fluid counterparts. Superfluidity allows different superfluid ~and superconducting! species of particles to have independent fluid flows, a consequence of which is that the fluid equations of motion contain as many fluid element velocities as superfluid species. Whenever the particles ...
متن کاملRelativistic mean-field dynamics of giant resonances
Models based on quantum hadrodynamics provide a consistent description of the nuclear many-body system in terms of interacting baryons and mesons. In the self-consistent mean-field approximation, the time-dependent model has been applied in the analysis of the dynamics of giant resonances. The calculated excitation energies and transition densities of isoscalar giant monopole resonances, restri...
