Title: Low energy determination of the QCD strong coupling constant on the lattice

Abstract

Here we present a determination of the strong coupling constant from lattice QCD using the moments of pseudo-scalar charmonium correlators calculated using highly improved staggerered quark action. We obtain a value αs( μ = mc) = 0.3397(56), which is the lowest energy determination of the strong coupling constant so far.
