摘要：Screening properties of the quark gluon plasma are studied from the Polyakov-line correlations in lattice QCD simulations with two flavors of improvedWilson quarks at temperatures T=Tpc '1–4 where Tpc is the pseudocritical temperature. Using the Euclidean-time reflection symmetry and the charge conjugation symmetry, we introduce various types of Polyakov-line correlations and extract screening masses in magnetic and electric sectors. We find that a ratio of the screening masses in the electric sector to the magnetic sector shows qualitative agreement with a prediction from the dimensionally-reduced effective field theory and theN =4 supersymmetric Yang-Mills theory at 1:3 < T=Tpc < 3.
