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

TL;DR

This paper introduces two new non-relativistic QCD-inspired potential models for quark-antiquark interactions, aiming to accurately describe meson spectra and compare with experimental data, identifying the more precise potential.

Contribution

It proposes two novel derived QCD potential models for meson spectra, with one showing superior agreement with experimental data.

Findings

One potential model matches experimental meson spectra more accurately.

The models incorporate Coulomb-like, linear confinement, and spin-spin interactions.

Comparison favors one potential over the other in precision.

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.
