Perturbative quark bound states in pNRQCD

Abstract

In the framework of the QCD effective field theory called potential Non-Relativistic QCD, we explore quark-antiquark bound systems that may be dominated by the perturbative interaction and we discuss the extent of validity of such a picture. Some phenomenological implications are outlined.
