Abstract: We show that the splitting between the light pseudoscalar and vector meson states is due to the strong short-range attraction in the S-1(0) sector which makes the pion and the kaon light particles. We use a light-cone QCD-inspired model of the mass squared operator with harmonic confinement and a Dirac-delta interaction. We apply a renormalization method to define the model, in which the pseudoscalar ground state mass fixes the renormalized strength of the Dirac-delta interaction.
