Charmonium sum rules applied to a holographic model

TL;DR

This paper applies heavy-quark QCD sum rules to a holographic model of charmonium, showing strong agreement with experimental data and suggesting the model's consistency with QCD sum rules at zero temperature.

Contribution

It demonstrates that a holographic gauge/gravity duality model can accurately reproduce charmonium properties consistent with QCD sum rules.

Findings

Strong agreement between holographic model and experimental data

Model consistent with heavy-quark QCD sum rules at zero temperature

Validates holographic approach for heavy-quark systems

Abstract

The heavy-quark QCD sum rules are applied to a model of charmonium based upon the gauge/gravity duality. We find that there is strong agreement between the moments of the polarization function calculated from the holographic model and the experimental data suggesting that the model is consistent with the heavy-quark QCD sum rules at zero temperature.
