Nonperturbative IR limit of the gluon polarization tensor at
Kalashnikov O. K.
The nonperturbative IR limit of the trace of the transverse components of the gluon polarization tensor is calculated in the Feynman gauge for Τ ^0 in SU(N) gluodynamics. The result of the calculation is a logarithmic function multiplied by a power law and is not amenable to a series expansion in g2.
