Description
Summary:The static longitudinal and transverse gluon propagators in the Landau gauge are studied in [Formula omitted] lattice QCD with nonzero isospin chemical potential [Formula omitted]. 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 [Formula omitted] with suppression increasing with increasing [Formula omitted]. It is found, respectively, that the electric screening mass is increasing with increasing [Formula omitted]. Additionally, we analyze the difference between two propagators as a function of the momentum and thus compare interactions in chromoelectric and chromomagnetic sectors.
