Gluon propagators in $$2+1$$ 2 + 1 lattice QCD with nonzero isospin chemical potential
Abstract The static longitudinal and transverse gluon propagators in the Landau gauge are studied in $$2+1$$ 2 + 1 lattice QCD with nonzero isospin chemical potential $$\mu _I$$ μ I . Parameterization of the momentum dependence of the propagators is provided for all values of the chemical potential...

| description | Abstract The static longitudinal and transverse gluon propagators in the Landau gauge are studied in $$2+1$$ 2 + 1 lattice QCD with nonzero isospin chemical potential $$\mu _I$$ μ I . 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 $$\mu _I$$ μ I with suppression increasing with increasing $$\mu _I$$ μ I . It is found, respectively, that the electric screening mass is increasing with increasing $$\mu _I$$ μ I . Additionally, we analyze the difference between two propagators as a function of the momentum and thus compare interactions in chromoelectric and chromomagnetic sectors. |
