Abstract

A heavy quark antiquark potential is suggested connecting asymptotic freedom and quark confinement in a unified way. Theα g (q 2) calculated using Borel summation technique with three loop agrees with the two loopβ-function up tog 2/4π≅ 1.1 but changes appreciably afterg 2/4π=1.5. The potential so derived satisfactorily explains the \(c\bar c\)and \(b\bar b\)spectrum.
