The heavy quark potential in pNRQCD

TL;DR

This paper discusses the static potential of heavy quarkonium within potential NRQCD, providing quantitative insights in the regime where the quark mass times velocity greatly exceeds the QCD scale, using next-to-leading order multipole expansion.

Contribution

It offers a detailed analysis of the heavy quarkonium potential in pNRQCD at next-to-leading order, focusing on the regime where $mv >> \\Lambda_{QCD}$, which was less explored before.

Findings

Quantitative statements about the static potential in the specified regime.

Application of next-to-leading order multipole expansion.

Insights into the behavior of heavy quarkonium at high mass and velocity regimes.

Abstract

The heavy quarkonium static potential is discussed within the framework of potential NRQCD. Some quantitative statements are made in the kinematical situation $mv >> \Lambda_{\rm QCD}$ at the level of accuracy of the next-to-leading order in the multipole expansion.
