On Exotic Systems of Baryons in Chiral Soliton Models

TL;DR

This paper investigates quantum corrections in chiral soliton models for exotic baryons, showing that these corrections stabilize systems with higher baryon numbers and suggesting potential additional binding in strange skyrmion crystals.

Contribution

It provides a simple expression for zero mode quantum corrections depending on strange inertia and analyzes their stabilizing effect on exotic baryonic systems.

Findings

Quantum corrections stabilize higher baryon number systems.

Strange skyrmion crystals may have increased binding energy.

Zero mode quantum corrections depend on strange inertia.

Abstract

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 systems the stronger the greater their baryon number is. Furthemore, systems are considered which could be interpreted in the quark model language as containing additional $q\bar q-$pairs. It is argued that a strange skyrmion crystal should have additional binding in comparison with the $SU(2)-$quantized neutron crystal.
