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, Λ+c and Λb0 for differentes values of the regularization cut-off parameter with a fixed nucleon mass. Our results are remarkable agreement with the experimental data.
