Ground-state baryons in a quark model with hyperfine interactions

Abstract

We discuss the ground-state baryons $N$, $\ensuremath{\Lambda}$, $\ensuremath{\Sigma}$, $\ensuremath{\Xi}$, $\ensuremath{\Delta}$, ${\ensuremath{\Sigma}}^{*}$, ${\ensuremath{\Xi}}^{*}$, and $\ensuremath{\Omega}$ in a quark model with flavor-independent confinement and color hyperfine interactions. We include the effects of wave-function distortions for unequal quark masses as well as interband mixing via the hyperfine interactions and find good agreement with the observed masses.
