Regularization of a Light-Front Qqq Model

Abstract

We study the mass of the ground state of Qqq system using differents regularization schemes of the relativistic integral equation obtnaide with a flavor independente contact interaction in a QCD-inspired model. We calculated the masses of the spin 1/2 low-lying states of the ${\Lambda }^0$, ${\Lambda }_c^{+}$ and ${\Lambda }_b^0$ for differentes values of the regularization cut-off parameter with a fixed nucleon mass. Our results are remarkable agreement with the experimental data.
