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 Λ0\Lambda^0, Λc+\Lambda^{+}_c and Λb0\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.
