The Strong Coupling from Quarkonia
Aida X. El-Khadra
TL;DR
This paper reviews how the strong coupling constant is determined from quarkonia using lattice QCD and compares these results with perturbative QCD findings.
Contribution
It provides a comprehensive comparison of lattice QCD and perturbative QCD methods for extracting the strong coupling from quarkonia.
Findings
Lattice QCD results are consistent with perturbative QCD within uncertainties.
The review highlights the current precision and challenges in determining from quarkonia.
Discrepancies between methods are analyzed and discussed.
Abstract
The status of determinations of from quarkonia using lattice QCD is reviewed. We compare the results with those obtained from perturbative QCD.
