Heavy quarkonia description from an energy dependent quark-antiquark potential

TL;DR

This paper introduces an energy-dependent potential model for heavy quarkonia that incorporates lattice QCD results, successfully describing known states and new charmonium-like states.

Contribution

It presents a novel energy-dependent quark-antiquark potential model that integrates unquenched lattice QCD results into quark models.

Findings

Qualitative agreement with experimental charmonium and bottomonium spectra

Reasonable quantitative reproduction of known states

Effective description of new charmonium-like states

Abstract

We model the spectral effect of open flavor meson-meson thresholds in heavy quarkonia. The proposed energy dependent quark-antiquark static potential tries to incorporate in a quark model scheme the results from unquenched lattice calculations. A good qualitative and a reasonable quantitative description of charmonium and bottomonium, including the "new charmonium-like" states, is obtained.
