Title: QCD running coupling with diquarks

Abstract

The running coupling constant is evaluated at order g2 within an extended model of Quantum Chromodynamics with color antitriplet scalar diquarks. Asymptotic freedom is valid also when the matter fields are originated by diquarks composed by strongly correlated pair of quarks. Diquarks slightly enhances {alpha}QCD at scales about 1 GeV, in qualitative agreement with data.
