Ground State Masses and Biding Energies of the Nucleon, Hyperon and Heavy Baryons in a Light-Front Model

Abstract

The ground state masses and binding energies of the nucleon, ${\Lambda }^0$, ${\Lambda }_c^{+}$, ${\Lambda }_b^0$ are studied within a constituent quark QCD-inspired light-front model. The light-front Faddeev equations for the $Qqq$ composite spin 1/2 baryons, are derived and solved numerically. The experimental data for the masses are qualitatively described by a flavor independent effective interaction.
