Masses of light mesons in the relativistic quark model

Abstract

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