    • Abstract

       

      A heavy quark antiquark potential is suggested connecting asymptotic freedom and quark confinement in a unified way. Theαg(q2) calculated using Borel summation technique with three loop agrees with the two loopβ-function up tog2/4π≅ 1.1 but changes appreciably afterg2/4π=1.5. The potential so derived satisfactorily explains the $$c\bar c$$and $$b\bar b$$spectrum.
