After an introduction of solitons with emphasis in elementary particle theory, we present a non-linear O(3) model in (2 + 1) dimensions modified by the addition of both a potential-like and a Skyrme-like term. We study some basic scattering properties of the model via numerical simulation using a general field configuration. The skyrmion-scattering is found to be quasi-elastic, the skyrmions’ energy density profiles remaining unscathed after collisions. In low-energy processes the skyrmions exhibit back-scattering, while at larger energies they scatter at right angles. These results confirm those obtained in previous investigations, in which a similar problem was studied for a different choice of the potential-like term. |
