摘要
The role of zero mode quantum corrections to the energy of baryonic systems with exotic quantum numbers (strangeness) is discussed. A simple expression for the contribution depending on strange inertia is obtained in the SU (3)-collective coordinate quantization approach and it is shown that this correction stabilizes the system the stronger the greater their baryon number is. Furthermore, systems are considered which could be interpreted in the quark model language as containing additional qqBAR-pairs. It is argued that a strange skyrmion crystal should have additional binding in comparison with the SU (2)-quantized neutron crystal.
