Large-Nc Regge models and the <A^2> condensate

TL;DR

This paper investigates how the <A^2> gluon condensate influences the alignment of Regge models with the operator product expansion in meson correlators, aiming to improve theoretical understanding of QCD.

Contribution

It introduces a novel approach to incorporate the <A^2> condensate into Regge models for better matching with QCD predictions.

Findings

The <A^2> condensate significantly affects meson correlator modeling.

Inclusion of <A^2> improves the consistency between Regge models and OPE.

Results suggest a refined understanding of non-perturbative QCD effects.

Abstract

We explore the role of the <A^2> gluon condensate in matching Regge models to the operator product expansion of meson correlators.
