Relativistic dynamics of Qqq systems

Abstract

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, ${\Lambda }^0$, ${\Lambda }_c^{+}$ and ${\Lambda }_b^0$ are found and compared to the experimental data. The data is qualitatively described with a flavor independent effective interaction.
