Quark confinement in the analytic approach to QCD

Abstract

The interquark potential is constructed by making use of the new analytic running coupling in QCD. This running coupling arises under ``analytization'' of the renormalization group equation. The rising behavior of the interquark potential at large distances, which provides the quark confinement, is shown explicitly. The estimation of the parameter ${\Lambda }_{QCD}$ is obtained.
