We apply the strong πNN form factor, which emerges from the Skyrme model, in the two-nucleon system using a one-boson-exchange (OBE) model for the nucleon-nucleon (NN) interaction. Deuteron properties and phase parameters of NN scattering are reproduced well. In contrast to the form factor of monopole shape that is traditionally used in OBE models, the Skyrme form factor leaves low momentum tra...

The two-nucleon interaction derived in chiral effective field theory is used to investigate the saturation properties of symmetric nuclear matter at next-to-leading order. Pauli blocking effects in the two-pion exchange diagrams are shown to produce an effective attraction in nuclear matter.

Static magnetic quadrupole moment of a nucleus, induced by T-and P-odd nucleon-nucleon interaction, is investigated in the single-particle approximation. Models are considered allowing for analytical solution. The problem is also treated numerically in a Woods-Saxon potential with spin-orbit interaction. The stability of results is discussed.

A Skyrme type Lagrangian for a skyrmion imbedded in a baryon rich environment is proposed. The dependence of static nucleon properties and nucleon nucleon tensor interaction on nuclear density is investigated.

The solution for the nucleon-nucleon (NN) T matrix in the framework of the covariant Bethe-Salpeter approach for a two spin-one-half particle system with a separable kernel of interaction is analyzed. The explicit analytical connection between parameters of the separable kernel and low energy scattering parameters, deuteron binding energy and phase shifts is established. Covariant separable ker...
