E. Megias, E. Ruiz Arriola, L.L. Salcedo
TL;DR
This paper investigates the relationship between perturbative series and power corrections in QCD at various temperatures, providing evidence for a strong correlation that supports a duality conjecture.
Contribution
It introduces a method to analyze correlations between perturbative and non-perturbative contributions in QCD, validating the duality conjecture through empirical observations.
Findings
Strong correlation observed between perturbative and non-perturbative contributions
Supports the duality between perturbation series and power corrections in QCD
Applicable at both zero and finite temperature regimes
Abstract
The duality between QCD perturbative series and power corrections recently conjectured by Narison and Zakharov is analyzed. We propose to study correlations between both contributions as diagnostics tool. A very strong correlation between perturbative and non perturbative contributions is observed for several observables at zero and at finite temperature supporting the validity of the dual description.
