Flavoured multiskyrmions

Abstract

Static properties of multiskyrmions with baryon numbers up to 8 are calculated starting from recently given rational map ansaetze. The spectra of baryonic systems with strangeness, charm and bottom are estimated 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 quantized strange multiskyrmion with baryon number 6 or 7 and large value of strangeness. In agreement with previous observation, it is argued that baryonic systems with charm or bottom quantum numbers have more chances to be bound with respect to strong interactions than strange baryonic systems.
