Semirelativistic constituent-quark model with Goldstone-boson-exchange hyperfine interactions

We address the semirelativistic constituent-quark model with linear confinement and a hyperfine interaction deduced from Goldstone-boson exchange. In the version where the latter is represented by pseudoscalar meson exchange (π, K, η, η prime)and restricted to the spin-spin component only a unified description of all light- and strange-baryon spectra is provided in close agreement with phenomenology. We discuss the extension of the model that includes also the tensor components of the pseudoscalar meson exchange and in addition vector-meson (ρ, ω, K*, φ) and scalar-meson (σ) exchanges. A preliminary version thereof provides a description of the baryon spectra with similar good quality
