Canonically quantized soliton in the bound state approach to heavy baryons in the Skyrme model

TL;DR

This paper extends the Skyrme model for heavy baryons by canonically quantizing the soliton in various SU(3) representations, revealing a stabilizing negative mass term and analyzing the spectra of strange, charm, and bottom baryons.

Contribution

It introduces a canonical quantization approach for the soliton in arbitrary SU(3) representations, including a negative mass term that stabilizes the solution and explores representation-dependent spectra.

Findings

Negative mass term stabilizes the soliton.

Spectra depend on the SU(3) representation.

Results compared with empirical baryon spectra.

Abstract

The bound state extension of Skyrme's topological soliton model for the heavy baryons is quantized canonically in arbitrary reducible representations of the SU(3) flavor group. The canonical quantization leads to an additional negative mass term, which stabilizes the quantized soliton solution. The heavy flavor meson in the field of the soliton is treated with semiclassical quantization. The representation dependence of the calculated spectra for the strange, charm and bottom baryons is explored and compared to the extant empirical spectra.
