Relativistic dynamics of Qqq systems

The bound state of constituent quarks forming a $Qqq$ composite baryon is investigated in a QCD-inspired effective light-front model. The light-front Faddeev equations are derived and solved numerically. The masses of the spin 1/2 low-lying states of the nucleon, ${\mathrm{\Lambda }}^0$, ${\mathrm{\Lambda }}_c^{+}$ and ${\mathrm{\Lambda }}_b^0$ are found and compared to the experimental data. The data is qualitatively described with a flavor independent effective interaction.
