Heavy-Quarkonium Potential from the Lattice Gluon Propagator

TL;DR

This paper introduces a novel approach to calculating heavy-quarkonium spectra by replacing the traditional gluon propagator with one derived from lattice simulations, and compares the results to the Cornell potential model.

Contribution

It presents a lattice-based gluon propagator method for quarkonium spectrum calculation, offering an alternative to the conventional Cornell potential approach.

Findings

Lattice-derived propagator yields spectra comparable to Cornell model

Interquark distances estimated in both models

Potential differences analyzed for heavy quarkonia

Abstract

We consider the potential-model approach for obtaining the spectrum of charmonium and bottomonium, replacing the usual gluon propagator by one obtained from lattice simulations. The resulting spectra are compared to the corresponding ones in the Cornell-potential case. We also estimate the interquark distance in both cases.
