Relativistic Model Field Theory with Finite Self-Masses

Relativistic 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...

Effective field theory: A complete relativistic nuclear model

We analyzed the results for finite nuclei and infinite nuclear and neutron matter using the standard σ−ω model and with the effective field theory. For the first time, we have shown here quantitatively that the inclusion of self-interaction of the vector mesons and the cross-interaction of all the mesons taken in the theory explain naturally the experimentally observed softness of equation of s...

On the relativistic field theory model of the deuteron II

The relativistic field theory model of the deuteron suggested in [1] is revised and applied to the calculation of the cross sections of the low–energy radiative neutron– proton capture n + p → D + γ and the low–energy two–proton fusion p + p → D + e+ + νe. For the low–energy radiative neutron–proton capture n + p → D + γ our result agrees well with both the experimental data and the potential m...

The nucleon and mesons effective masses in the Relativistic Mean-Field Theory

The nucleon and meson effective masses in the nonlinear Relativistic Mean-Field Theory (RMF) introducing a ω− ρ coupling is explored. It is shown that, in contrast to the usual Walecka model, not only the effective nucleon mass meff,N but also the effective ρ meson mass meff,ρ and the effective ω meson mass meff,ω are nucleon density dependent.
