Nucleon-Antinucleon Interaction from the Skyrme Model: II. Beyond the Product Ansatz
Yang Lu, Pavlos Protopapas, R. D. Amado
Abstract
We calculate the full static interaction of a Skyrmion and an anti-Skyrmion as a function of separation and relative grooming. From this, using projection methods and Born-Oppenheimer mixing, we obtain the nucleon antinucleon interaction. We find agreement with the major features of the empirical interaction including the strong central attraction and the sharp onset of annihilation at about 1 fm.
