Static N-N and N-Formula Interactions in the Skyrme Model

Abstract

Static nucleon-nucleon (N-N) and nucleon-antinucleon (N-N) interactions in the Skyrme model are calculated using the so-called product approximation. Properties of the obtained interactions are examined and discussed in terms of the G-parity transformation based on the meson exchange picture. It is shown that the state-independent repulsive term found in the N-N potential remains completely unchanged in the N-N case, which is at variance with the ω-meson exchange effect. In long and intermediate range parts of the isovector spin-spin and tensor interaction, one pion and ρ-meson like effects are clearly exhibited. A feature possibly attributable to the A₁-meson is also noticed.
