. Parameterization of the momentum dependence of the propagators is provided for all values of the chemical potential under study. We find that the longitudinal propagator is infrared suppressed at nonzero $$\mu _I$$

with suppression increasing with increasing $$\mu _I$$

. It is found, respectively, that the electric screening mass is increasing with increasing $$\mu _I$$

. Additionally, we analyze the difference between two propagators as a function of the momentum and thus compare interactions in chromoelectric and chromomagnetic sectors.
