# Relativistic phenomenology of meson spectra with a covariant quark model in Minkowski space

## TL;DR

This paper develops a covariant quark model using the Covariant Spectator Theory to accurately predict meson spectra and wave functions, demonstrating strong agreement with experimental data and testing the model's predictive capabilities.

## Contribution

It introduces a covariant formalism for meson spectra using CST, providing precise predictions with minimal parameters and enabling direct testing of covariant kernels.

## Key findings

- Accurately reproduces experimental meson spectra
- Validates the predictive power of covariant kernels
- Uses a minimal set of global parameters

## Abstract

In this work, we perform a covariant treatment of quark-antiquark systems. We calculate the spectra and wave functions using a formalism based on the Covariant Spectator Theory (CST). Our results not only reproduce very well the experimental data with a very small set of global parameters, but they also allow a direct test of the predictive power of covariant kernels.
