On a recent calculation of the mass spectra of quarkonia using the Cornell potential with spin-spin interactions

TL;DR

This paper critically examines a recent study on quarkonia mass spectra, revealing that the original authors mistakenly used the Kratzer-Fues potential instead of the Cornell potential due to an invalid transformation.

Contribution

It clarifies the actual potential used in previous work, correcting a common misconception about the application of the Cornell potential with spin-spin interactions.

Findings

The original study used the Kratzer-Fues potential unintentionally.

An invalid transformation led to the misidentification of the potential.

The correction impacts the interpretation of quarkonia mass spectra calculations.

Abstract

We analyse a recent application of the Cornell potential with spin-spin interaction to the mass spectra of quarkonia and show that the authors have in fact used the Kratzer-Fues potential. They inadvertently converted one potential into the other by means of an invalid transformation.
