Spectra of quark-antiquark bound states via two derived QCD potential

Abstract

In the current paper, we propose two types of quark-antiquark interactions, which may be tailored to describe various meson sectors. The interactions contain Quantum Chromodynamics (QCD) inspired components, such as the Coulomb-like interaction, the confinement linear potential, and the spin-spin interaction. Our scheme relies on the non-relativistic quark model through the introduction of two derived QCD potential models. The application of the two proposed potentials resulted in spectra for quark-antiquark bound states, which are compared with published experimental data. We found that one of the two potentials is favored over the other in terms of high precision comparisons.
