Multibaryons with strangeness, charm and bottom
- 25 Downloads
The spectra of baryonic systems with strangeness, charm and bottom are considered within a “rigid oscillator'' version of the bound state soliton model. The static properties of multiskyrmions, of baryon number up to B=8, are calculated using the recently suggested rational map ansaetze as starting field configurations. The property of binding of flavoured mesons by an SU(2) skyrmion is proved rigorously within this model. Binding energy estimates are made of the states with largest isospin which can appear as negatively charged nuclear fragments and for states with zero isospin – fragments of “flavoured'' nuclear matter. It is shown that for all types of flavour and for \(|F| \leq 2\) the isoscalar baryonic systems have a better chance to be stable against strong and electromagnetic interactions than those with nonzero isospin. Baryonic systems with charm or bottom quantum numbers are found to be bound more than strange baryonic systems.
