Self-consistent equation for the magnetic mass of a gluon
Kalashnikov O. K.
An equation is derived for the magnetic mass of a gluon with allowance for the entire series of nonperturbative diagrams for the polarization operator. The four-gluon vertex is eliminated in a self-consistent way. The calculation scheme is closed through the choice of a nonperturbative approximation of the three-gluon vertex. Ag4r2ln (μ/g1 Τ) behavior is predicted for the square magnetic mass of the gluon.
