Treatment of broken symmetry in the Faddeev approach to the strange baryon spectra
Joseph P. Day, Zoltan Papp
TL;DR
This paper calculates strange baryon masses using Faddeev equations within a relativistic quark model, explicitly incorporating broken SU(3)_F symmetry due to the strange quark's heavier mass.
Contribution
It introduces a method to explicitly include broken SU(3)_F symmetry in Faddeev calculations of strange baryons.
Findings
Successfully accounts for symmetry breaking in baryon mass calculations
Provides a relativistic treatment of the quark model
Enhances understanding of strange baryon spectra
Abstract
By solving the Faddeev equations we calculate the mass of the strange baryons in the framework of a relativistic constituent quark model. The Goldstone-boson-exchange quark-quark interaction is derived from symmetry, which is explicitly broken as the strange quark is much heavier. This broken symmetry can nicely be accounted for in the Faddeev framework.
