Contribution

It establishes the equivalence of Dirac and BFT schemes in quantizing the SU(2) Skyrmion, enhancing understanding of baryon quantization methods.

Findings

Energy spectrum matches BFT results

Dirac method with generalized momenta is effective

Consistent static baryon properties predictions

Abstract

In the framework of Dirac quantization, the SU(2) Skyrmion is canonically quantized to yield the modified predictions of the static properties of baryons. We show that the energy spectrum of this Skyrmion obtained by the Dirac method with the suggestion of generalized momenta is consistent with the result of the Batalin-Fradkin-Tyutin formalism.
