Standard Model Parameters from Quarkonia using Lattice QCD

Abstract

Quarkonia -- mesons made of a heavy quark and anti-quark -- have been extensively studied experimentally. Theoretical calculations of quarkonia based on lattice QCD are possible with control over the systematic errors. The comparison with experimental measurements of the quarkonia spectra leads to determinations of Standard Model parameters: the strong coupling, ${\alpha }_s$, and the heavy quark masses.
