Magnetic and Electric Screening Mass in Two-Flavors of Lattice QCD Simulations
Electric and magnetic screening masses in the quark-gluon plasma are studied from lattice QCD with two flavors of improved Wilson 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 introd...

| Summary: | Electric and magnetic screening masses in the quark-gluon plasma are studied from lattice QCD with two flavors of improved Wilson 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-loop correlation under the Coulomb gauge fixing and extract the electric screening mass (mE) and the magnetic screening mass (mM), separately. We find the inequality mM ≪ mE ≪ 2 mM in the temperature interval we have studied. Also the screening ratio mE /mM ≃1.5 found agrees well with the prediction using AdS/CFT correspondence. |
