Flavored multiskyrmions

Abstract

Static properties of multiskyrmions with baryon numbers up to 8 are calculated on the basis of the recently given rational map Ansätze. The spectra of baryonic systems with strangeness, charm, and bottom are considered within a “rigid oscillator” version of the bound state soliton model. It is suggested that the recently observed negatively charged nuclear fragment can be considered as a quantized strange multiskyrmion with B=6 or 7. In agreement with previous observations, baryonic systems with charm or bottom have a better chance of being bound by the strong interactions than do strange baryonic systems.
