Masses of light mesons in the relativistic quark model

The masses of the S-wave mesons consisting of the light (u, d, s) quarks are calculated within the constituent quark model. The relativistic Schrodinger-like equation with a confining potential is numerically solved for the complete relativistic qq potential including both spin-independent and spin-dependent terms. The obtained masses of the ground state pi, p, K, K* and phi mesons and their first radial excitations are in a reasonably good overall agreement with experimental data.
