Description

A theory of a non-Abelian gauge field is considered on the basis of an effective Lagrangian that possesses the property of asymptotic freedom. In this theory, the confinement-deconfinement phase transition has a nontrivial scenario according to which the two phases may exist in the same spacetime region. In the low-momentum region vertical bar p2 vertical bar < ΛQCD2, we have a confining regime in the presence of a gluon condensate, while, in the high-momentum region vertical bar p2 vertical bar >> ΛQCD2, perturbative QCD holds. An iterative scheme for refining parameters of the effective Lagrangian is outlined
