TL;DR: In this paper, the authors extend previous work on high energy nuclear collisions in the Color Glass Condensate model to study collisions of finite ultrarelativistic nuclei, and show that the gluon distribution in the nuclear wavefunction before the collision is significantly suppressed below the saturation scale when compared to the simple McLerran-Venugopalan model prediction, while the behavior at large momentum p T ⪢ Λ s remains unchanged.

TL;DR: In this paper, a new parameterization of the effective nucleon-nucleon Gogny interaction is proposed, which reproduces the neutron matter equation of state much better than the commonly used D1S Gogy interaction and furthermore reduces the binding energies' drift for the major part of the isotopic chains.

TL;DR: In this article, an attempt to account for nuclear saturation and shell structure in terms of manybody forces that are derived from mesons that obey a nonlinear wave equation was made.
Abstract: This paper develops an attempt to account for nuclear saturation and shell structure in terms of manybody forces that are derived from mesons that obey a nonlinear wave equation. Classical field theory is used, and in some cases the practical difficulties of obtaining numerical answers are reduced by employing a variation method. Apart from a cutoff, which appears in this particular form of the theory but could be eliminated, there are two parameters in the theory; they can be chosen so that nuclear matter has a stable density equal to the observed value, and a variational binding energy equal to 42 percent of the observed value, thus approximately accounting for saturation. The two-nucleon interaction has the observed order of magnitude in empty space, and is greatly reduced within nuclei. This suppression of two-body interactions in favor of the interaction of each nucleon with the average nucleon density in heavy nuclei may account for the independent-particle model and hence for shell structure. Although the theory does not account for magnetic moments, it indicates that a more realistic version (for example, a nonlinear pseudoscalar theory) may predict a reduction of the anomalous magnetic moments of nucleons within nuclei. According to a recent suggestion of Bloch, this could account for the deviations of the magnetic moments of even-odd nuclei from the Schmidt lines. The nonlinearity also has the consequence that mesons are scattered from nuclei as though by a strong repulsive potential. The relation of this effect to current observations on interactions between mesons and nuclei is briefly discussed.

TL;DR: In this article, the relativistic Hartree-Fock (HF) equations for an infinite system of mesons and baryons were derived based on a diagrammatic approach and Dyson's equation for the baryon propagator.

TL;DR: In this article, the spin-orbit force in more general chiral effective field theories of nuclei is examined, with an emphasis on the role of the tensor coupling of the isoscalar vector meson (ω) to the nucleon.
