Renormalized Quarkonium

TL;DR

This paper extends a renormalization approach with boundary conditions to analyze the full spectrum of charmonium and bottomonium, comparing predictions with existing models and literature assignments.

Contribution

It introduces a comprehensive renormalization method for quarkonium spectra and compares results with traditional regularized quark models.

Findings

Predicted spectra align with literature assignments

Renormalization approach provides consistent results across states

Comparison shows advantages over regularized models

Abstract

We extend our previous study of the vector charmonium states within a renormalization approach with boundary conditions to the full spectrum of charmonium and bottomonium. On the light of the predicted spectrum we comply to assignments suggested in the literature. A comparison with the regularized quark model is also included.
