Skyrmions from SU(3) harmonic maps and their quantization

Static properties of SU(3) multiskyrmions with baryon numbers np to 6 are e stimated. The calculations are based on the recently suggested generalizati on of the SU(2) rational map ansatze applied to the SU(3) model. Both SU(2) embedded skyrmions and genuine SU(3) solutions are considered and it is sh own that although, at the classical level, the energy of the embeddings is lower, the quantum corrections can alter these conclusions. This correction to the energy of the lowest state, depending on the Wess-Zumino term, is p resented in the most general case. (C) 2000 Elsevier Science B.V. All right s reserved.
