Title: Nucleon-antinucleon interaction from the modified Skyrme model

Abstract

We calculate the static nucleon-antinucleon interaction potential from the modified Skyrme model with an additional B{sup {mu}}B{sub {mu}} term using the product ansatz. The static properties of the single baryon are improved in the modified Skyrme model. State mixing is taken into account by perturbation theory, which substantially increases the strength of the central attraction. We obtain a long- and mid-range potential which is in qualitative agreement with some phenomenological potentials.
