Abstract

Abstract We apply Bogolubov approach to QCD to demonstrate a spontaneous generation of three-gluon gauge invariant effective interaction which contributes significantly at the infrared region. The contribution of this interaction to α s ( p 2 ) leads to description of its behavior in correspondence to phenomenology and lattice calculations without introduction of any additional parameter.
