Renormalons in static QCD potential: review and some updates

TL;DR

This paper reviews the current understanding of renormalons in the static QCD potential, discusses estimates of the normalization constant of the u=3/2 renormalon, and proposes improvements to these estimates.

Contribution

It provides a comprehensive review of renormalons in static QCD potential and introduces a new method to refine the normalization constant estimate.

Findings

Updated estimate of the u=3/2 renormalon normalization constant

Proposed a new approach to improve the estimate

Reviewed current understanding of renormalons in static QCD potential

Abstract

We give a brief review of the current understanding of renormalons of the static QCD potential in coordinate and momentum spaces. We also reconsider estimate of the normalization constant of the $u=3/2$ renormalon and propose a new way to improve the estimate.
