| Abstract: | It is shown that the effective gluon propagator in the global color symmetry model can be calculated in the instanton dilute liquid approximation. The calculated effective gluon propagator is consistent with the general command on the qualitative features of the gluon propagator, i.e., (i) the gluon propagator is significantly enhanced at small space-like k2, and (ii) for k2 > 1.5 GeV2 the perturbative results are quantitatively reliable. |
