Quarkonium in the Wilson loop formalism: new perspectives

TL;DR

This paper reviews the current understanding of heavy quark interactions using the Wilson loop formalism within the NRQCD effective theory, highlighting new perspectives on chromoelectric and chromomagnetic insertions.

Contribution

It introduces new perspectives on quarkonium interactions by analyzing Wilson loop insertions within the NRQCD framework.

Findings

Enhanced understanding of chromoelectric and chromomagnetic contributions

Clarification of the Wilson loop formalism in heavy quark interactions

Potential implications for quarkonium phenomenology

Abstract

We review the present knowledge on the heavy quark interaction. The framework is the NRQCD effective theory and the interaction is expressed in terms of Wilson loop chromoelectric and chromomagnetic insertions.
