TL;DR
This paper derives constituent quark masses by fitting meson and baryon masses using color-spin and flavor-spin interaction models, highlighting the consistency of results across different hyperfine interaction approaches.
Contribution
It introduces a method to determine constituent quark masses using SU(3) flavor symmetry breaking within two hyperfine interaction models, Fermi-Breit and Glozman-Riska.
Findings
Constituent quark masses are similar across models.
Mass formulas fit experimental data well.
Hyperfine interactions influence quark mass estimates.
Abstract
We use the color-spin and flavor-spin interaction Hamiltonians with SU(3) flavor symmetry breaking to obtain meson and baryon mass formulas. Adjusting these masses with experimental masses we determine the constituent quark masses. We discuss the constituent quark masses obtained from meson and baryon mass fits. The results for constituent quark masses are very similar in case of two different phenomenological models: Fermi-Breit and Glozman-Riska hyperfine interactions.
