QCD零温和有限温下微扰理论与功率修正的相关性

Correlations between perturbation theory and power corrections in QCD at zero and finite temperature

E. Megias, E. Ruiz Arriola, L. L. Salcedo

摘要:

分析了Narison和Zakharov最近提出的QCD微扰级数与幂修正之间的对偶性。我们建议研究这两种贡献之间的相关性作为诊断工具。一个非常强的微扰和非微扰的贡献之间的相关性观察到几个观测值在零和有限的温度支持的双重描述的有效性。

英文摘要:

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.
